Oh, you'll definitely pull out of this then! It really does seem like this trying event in your life has hit your motivation, and that's totally normal and okay. Even as an artist, life happens and things will get in the way, and in those moments it's often best to just take a step back for a while, regroup, and come back stronger afterwards.
I'll offer my own story for perspective:
Drawing has always been one of my favorite things to do, and start in middle school I started to take it pretty seriously and practice hard! This lasted all the way up through highschool, and it was around that time that I got interested in making a comic. I thought up this big cool story, wrote out 8 chapters in novel form, drafted out the first chapter a bunch of times, but never got anywhere with it. I just kept drawing the characters a lot and improving my art instead.
Then college hit. I did an embarrassingly low amount of drawing for the 4 years I was in Uni. I just lacked the time and motivation to spend time drawing, even though I loved it. When I wasn't in class or working on homework, I'd usually rather hang out with friends or play video games. I did keep in touch with my design-oriented side, majoring in Architectural Design, so doing a bunch of drawings and renderings for class made me not want to do any more at home.
The summer following graduation I kinda looked back through a lot of my old drawings and was kind of sad that I lost touch with that hobby. So I kinda tried to pick it back up. I spent some time in August and September trying to re-reboot my comic idea from highschool, and got several pages drafted, but between the job hunt and eventual settling for a holiday season retail job, I kind of lost it again, which sucked... again. This was 2016, for reference.
Finally last year, summer 2017, I gathered my inner resolve to really start drawing again! I started out kind of slow, participating in some drawing events for a MMO I was playing at the time ("Draw the Character Above You" and a Fan Art Contest). Then when October rolled around, I decided to participate in Inktober for the first time ever! Although it was tough to force myself to draw every single day, it was really rewarding and helped set me on the path to being an artist again. From there I started lurking around these forums more often, watching youtube artists at work, targeting weak areas in my anatomy and such, and started practicing comics again! Finally in February this year I began planning a one-shot comic and finally got involved in art-related social media. Fast forward a few months and now I'm finally in the process of drawing the finalized pages! It feels great to finally be back at it :]
But the short of it is, there was a looooong period of time where I kind of abandoned art when life got in the way, and it kind of sucked. But as a hobby I enjoy immensely, it drew me back in, eventually! I agree with some of the other advice in this thread: maybe take a break for a while, then get back to drawing something, be it this same project, or a different one, or landscape paintings, or whatever! Hopefully it'll get the ball rolling
And even if this current project isn't the first thing you do, you can always hold onto it and revisit the idea later. I'd still like to draw the comic from highschool someday, although it needs a looooooot of work and editing down before I even consider it.
