I'm glad I could help 
and I hope your friend can get out of that dark place and begin drawing again.
All awesome advices ^^^! Another advice is maybe thinking about doing silly fanarts or simple quick one-page stand alone comic story.
The Satrians2 is a comic that takes a very long time for me to draw (about 12 hours for two-page spread). As much as I love that comics and its world, I do get a bit burned out spending so much time on it. So, I started what qq a fun short autobiographical comics (that's much quicker to make) to keep the whole comic-making thing enjoyable for me. It helps!
One great thing about art is that as your art improves (a lot of people hate their earlier chapters, which is a good thing -- a sign of improvement!) it's easier to semi-fix the situation. Just put a teaser image at the beginning of the series -- something like a collage of your favorite panels to show new readers the quality they can expect in later chapters.
Does your friend post on Tapastic? Please let her know that she's not alone. When I was at the rock bottom of that hole, it was incredibly frustrating (and baffling) that my fellow creators didn't seem to get what I was going through. I thought this was something that happened to everyone, but apparently not. (And in retrospect, I shouldn't have thought that because I used to never feel depressed about my lack of skills until a couple of years ago or so. The old me wouldn't have understood me, either.)
Boy. This one tore my heart out, keii4ii. It can be devastating. In fact, I think all too many of us know just how devastating the drive to create can be. It hounds you constantly, and you can't just forget about it. You've got to press forward, haha.
I'm glad you were able to reduce stress and figure out where you needed to go from there. Sometimes, the answer comes like a thunderbolt, although often enough we don't recognize it at the time. Good luck, keii.
first, accept the fact that dreams aren't that easy to achieve. in my expirience, I always thought that I can acchieve my dreams easily, but as you go you will see there are a lot better person other than you. of course you'll feel jealous when you see that there successful once and YOU ARE NOT. well, this world is unfair, not everyone can be famous and successful......... so then you will start going away and making haitus. DAMN' I 'VE BEEN THERE! AND I KNOW MOST OF US DOES. life is unfair but giving up will never be the answer.
second, GET UP AND GET YOUR ASS OUT OF THAT DEPRESSION! bro you have to motivate her.
third, keep going.... yeah it will be fatal but, you must continue for you to see the effect haha.
fourth, just look around you'll see you are not the only who is expiriencing that. in my expirience. my mom always say nonsense shit about me. she always say that what i am doing is nonsense and I can't get money with that! but it's not about money.. it's fashion!
fifth, beat yourself and enjoy the little things.. knowing that there is one person that likes your stuff is enough.... it will give you more motivation and contentment..
oh yes! I wanna share mine.... here: well I draw my stuffs with my phone and yes you can think of this as selfadvertising but the point is we need to get ,motivated by the things that we have not by the things that we don't have....

Agreed, @resleepingmarlon . You have a strong head on your shoulder. ^.^
That's very true. I have to keep reminding myself that I JUST started! Because you spend so much time and energy on your work, and then you get that eagerness to show it and expect a certain reaction or...i guess on this site at least for some people, a large amount of subscribers and that doesn't happen. It can dampen your spirits. But then I snap back and have to remind myself that you can't go 0 to 120mph. Everything comes in time, we just have to let ourselves have the time and be patient.
Thanks for your great response though!
She does, and I think she will thankfully come around.
But in her own time! I'm sharing with her all this.
Sometimes other artists do have a hard time understanding your frustration though. You get envious of others, or perhaps you belittle your own abilities or even you get stuck creatively, or all of the above, and it's incredibly damaging because you become your own worse enemy. But it's nice to know someone feels exactly the same.
I really don't know if me sharing this helps. But if it does, and I hope it does, then great.
My way of coping, at this point, is just doing the work on a routine basis regardless of how I'm 'feeling'. I'm older now and half my lifespan has been wasted away on fear and depression. That hasn't changed, the fear/anxiety part. But if I don't do this work now, I'll never get to do it, you know? No one will know what I've left undrawn.
That's what keeps me going, I guess. I'm going to die one day, it's now a point in time where it's realistically sooner rather then later, and I'd like the ideas that have been hounding me for so long in my head to actually just exist in some way, even if it's "not good enough". It'll never be good enough for me, but that's not the point of doing the work. It's just to get it out there, and to keep getting better with the frighteningly short time that I/We have.
More pratically, since this post sounds more Debbie Downer then I meant it, I thought I'd share a work method I picked up from another artist. KNKL cited a study performed by some warehouse that showed that it got more work out of it's workers that took many small, frequent breaks, then it did from workers that had very few, but longer breaks. To help with productivity I tend to do a lot of work based off that- around 24-26 minutes of "work" and then the 34-36 minutes of the rest of the hour is "play", whatever that entails for you. Alarms are practically required for this, heh.
I guess everyone has been through this but more than I had expected!
As part of a duo (two creators) it is hard, especially if your partner is the one lacking motivation. There were times when I felt like giving up and even going solo, but I just stopped and took a deep breathe in.
There are and will be days where ill just sit and would endure my brain screaming at me to stop what I loved to do. But what motivates me, is how much I've come along this journey; all those days I've spent writing on the stories, all those nights I've drawn and redrawn pages, all those times my files crashed, deleted, storyboards thrown in the garbage, when my partner, NooB, would shut down on me and visa versa. I would think and tell myself; if I stop now, then all that time was a waste. And 1 minute later ill be drawing again. 
There were times I've changed my art style drastically (because I was totally influenced by another creators' work, or other influences) and this would cause me to jump around and not find a solid base. I would recommend artists who do this to cut their ties to the internet for a while, and work on developing their own style: For me personally, this helped me regain CONFIDENCE in my works.
Just remember, the more blood, sweat and tears you put into your works, the better and more refined they become, thus the more satisfying you will ever be toward your works.
Even if you don't receive the same reaction from viewers and readers, only you will know that satisfying feeling of how much this work means to you.
For me, the works were not just a story anymore but became a way of expressing my story as well. Just behind the scenes 
(I don't even know if I'm making any sense...)

Uff, it just happened to me, some months ago, it got mixed with a extremely personal thing with a person and that person later bashing my work, which is why I'm still doubting about my story and even stopped drawing for a while.
But I truly think it's important to have a time to rest, body and mind, clear your mind by walking outside even if there's no place to go, but also I think we should make a personal work and admit we have abilities, imagination, talent, or all of them and think "maybe, I'm not in the leven I wanted but I'm still good". Then I thought, if I'm not happy about something in my story, I must just fix it, and for that we should give time to fix it and not push it otherwise we get stressed and stress is not of a help.
But I think the most important thing is to never give up, after all, this is what we all want to do, we can't give up in something we dream since long. Also find good people who can help you and tell you what is wrong in your work if you can't see it well, is also lot of help.
I don't know if this helps, but I hope so xD
Heavy drinking...then more of that.
To be honest the way I cope with it is producing content I like enough that even I no one else cared I could be happy it is out there. It isn't perfect but in the end I decide that it is better to make content than worry about whether what you are making is good enough. I'm lucky to have sickeningly supportive friends and I rarely get shit from people not liking my art. At the same time I know I can do better so that is what I strive for.
Now what motivates me is literally just striving to make professional content. I am totally cool with working the shit jobs I do as long as I am striving to become something more. It was a lot of soul searching for me to decide, but I think drawing is something I can really put my all into. If I never make it to the point I can live off my work well that would suck but, its much better than getting a graphics design degree in my opinion. Art is a fucking journey.
In the end the only person who determines whether or not you are an artist and this is what you want is you.
I go through self doubt whenever someone gives my work a thorough critique, I feel like I am not good enough, however, my brother Naoki told me " If you think you are never good enough you will never be happy". I have to take this to heart because I love art, it helps me express myself and its been there for my whole life.
As for lack of motivation I experience this if I work on one thing for too long, I start to burn out, so have trouble focusing. However, what makes me from completely abandoning my hobby due to boredom is other artists. Whenever I see antoher person's comic or they are progressing through their art career I say to myself, " I want my art to be at that level or recognition so it pushes me to pursue my passion further down the tunnel.
For me it's understanding Rome wasn't built in a day. That for me to be where I want to be it's going to take a lot of hard work and major frustration. It's all those days of hating what I'm drawing that makes those rare pieces I like all the better. I understand the struggle that got me there and I'm better for it. And honestly it scares me more to think of a day where I'm totally happy with my art, because that means I'm content and if you're content you're not growing as an artist.
sometimes i read comics or see cartoons or whatever that just give me the BURNING FIRE OF INSPIRATION and when that gets started i cant not draw/write. buuut that doesnt come along too much. so other times i day dream a lot about what itd be like if i ever get up near that JK Rowling throne. cuz thatd be rad. also (and this is kinda lame but get over it) i keep a folder of nice comments and junk i get on my comics and i look thru them if im feelin down
