I hope you're feeling better since this was posted in the forums! Looks like you had some down time to get outside and be away from the crap. That's good!
I really don't intend for this to sound snooty in any way, but I gotta share this observation that I'm sure others have gathered as well...
Online is pretty much a cesspool. In fact, a good percentage of online users are bots. And those bots don't even sound like bots from 2003 anymore, they sound like random strangers and can be indistinguishable unless you deep dive profiles and whatnot to get answers. (Don't do that, you'll drive yourself crazy. lol)
The real art community is irl. I understand that we're all online now, and we feel like we can't make any progress or traction with work and "success" without validation from internet platforms... but art has, and always will be, so much more than what's online nowadays. The vast majority of artists I've met in real life, at school, at my jobs--are genuinely wonderful people trying to lift each other up, learn from each other, and get better at their skills in their own time.
It's good that you want to value what other people say when they have critique for you... But critique should really be asked for, imo. I don't know what kind of bullying you are receiving, but sounds like they're just trying to dunk on you. And bullying is never warranted--even if you're a bully being bullied. It's just wrong and unproductive. Goes nowhere.
(Playing devil's advocate here, but... Always be self-analytical in what you put out on the internet. If someone responds with a genuine, "Hey, man. That's messed up to say." Then maybe think about why, and even have a talk with that person to get to the bottom of why a post or piece of your work caused a bad reaction. Always be learning. But again, from what you're saying, you're literally being bullied straight up. lol)
I concur with what other people are saying in the comments. Seriously, dude. If they're just hate comments, get rid of that crap. You don't need to see it, and others don't need to see it when they come to read your comic.
The art community is overwhelmingly wholesome and good to be a part of. But don't rely on social media platforms for it... go and put yourself out there in a local place, or take classes and meet people who are there to learn like you are. They're gonna be your friends for life.
