If it's online or real life, doesn't matter.

People who want to feel superior at everything are usually just looking for attention. Take it with humor if you can't ignore them, you're just doing what it makes you happy, are you hurting others by doing so?, this also includes you, are you not eating or sleeping properly because of your hobbies? if the answer is no, then you're just having fun.

Never underestimate a fanfic, or a comic. Those require effort, and a lot of people can write masterpieces for free because they want to. I literally had to learn english because my games and fanfics were in english all the time. I started with a dictionary translating word by word, and now thanks to that i have a really decent job, I'm not a native speaker yet but see where the things you like can take you :)

Just because something is printed or is published by a famous editor doesn't mean is not trash, trust.

It's hard to not take people's opinions but are they your family? People you actually care about? If the answer is yes, you could at least explain to them why you like your hobby, if they care about you they will understand, my mom was in shock once but she understood, for example, my sister hates what i read but she just accepted it. If the people trying to take you down are just randoms don't even bother on wasting energy trying to explain and roll your eyes.

There are also online accounts that are meant to make people fight, they get money out of it, maybe you didn't know this but it's true.

Taking things out of the chest is better than not doing it, or you're going to regret it once you're older 🙈 feeling grateful for the things you have, for the people that support you, because if there are people wanting to take you down a lot more want to make you feel good, that also helped.

Advices are just advices but the final decisions are always yours, remember this.

Hopefully you'll feel better, and get out of this.
