While I do agree 100% with @snailienz 's above comment, you also make some valid points, especially from an emotional/empathetic standpoint. There are tons of comics out there, and it becomes difficult to make yourself stand out and make yourself known, even to people who would really love your work.
HOWEVER. If you're working as hard and fast as you can, and you're not gaining traction (and of course your main goal is success and not just telling the story you want to tell), it may be time to step back, reevaluate your process, and figure out if you need to change tack.
For example, my first webcomic, Golden Years, I poured every ounce of time and effort I could into. I made full-color, 35-54 panel webtoon updates, with a complex style to sell my characters and story; I spend hours upon hours studying skeletons in poses and motions, clothing drapery, and even iron-age viking bakeries for what I considered the ideal amount of historical accuracy. I joined discord servers full of fellow comic creators, tried promoting my comic on multiple social medias; basically I put everything I could into it.
After months of hard work, do you know what I had to show for it? less than 30 subscribers, and one very burnt out comic creator. Now, this is a comic I enjoy telling, and if my sole goal was telling a story, my handful of subscribers that came to every weeks-apart update and liked it and left me comments that literally pulled me out of full burnout a couple of times would've been more than enough for me.
But my dream is to make a living off of comics, so I had to step back and reevaluate. (Plus, I was burnt out on golden years, and needed to do something different.)
So, when I was bashed over the head with inspiration for another comic, a comedy gag strip that I learned was much easier to bring in readers for early on, I went for it. It's a hard fact that, unless you have an existing following, it's very difficult to gain traction for stories without an easy hook, such as comedy, romance, and slice-of-life stories. Switching comics for me worked. I put in the same if not more effort marketing my earlier comic, but the genre and type of story was an easier sell for a casual reader. Plus, being able to update regularly every week helped.
Of course, my new comic is a comic I enjoy drawing, and especially enjoy seeing the reactions of my readers each update. So for the love of Sobek, don't switch to a comic you're not invested in, just because you think it'll gain popularity. That just lowers your odds.
I'm not saying that there's no opportunities that others might get that that you won't be able to grab yourself, or that luck isn't a factor (my friend who's a better artist than me and has been drawing comics longer than I have has only a tenth the popularity I do, so obviously luck was at play there). But there's always a way for you, personally, to improve your own odds. You just have to be honest with yourself to figure out how to improve.
