If the deeply personal information you've tossed out here is anything close to accurate, you were correct when you said you didn't have boundaries as a kid. And I'd guess the combination of traumatic events and innate chemical makeup makes it exceptionally hard for you to learn what proper boundaries are as an adult.
But understand that that lack of boundaries is what makes you so mad: you can't understand why people won't teach you what to do, won't react favorably to your lack of understanding about how to interact, and won't do what you say (that's you not understanding the limits of your control/boundaries), and you aren't able to differentiate between a gross violation of boundaries (touching you as a child) and something that is merely upsetting (people being rude).
It also aligns with both the fact that you didn't realize the difference between inspiration and copying, and the fact that when you finally got fed up with getting grief for it, you say you lied/said anything to make it stop, and you have been posting non-stop for marathon hours.
The other thing you do that works against you is you say, "why won't anyone tell me what to do," then respond by dismissing or mostly ignoring what they told you, instead putting your energy back to fighting...and usually revealing too much personal information, history, and emotions than someone with healthy boundaries would choose to do. Throwing out childhood molestation or threatening to post pictures of yourself in the bath are not healthy reactions in conflict (and they're so not solid or clever debate strategies, fyi). Confusion about boundaries all around.
Emotional regulation issues make interacting and perspective very challenging. You know this, and you've said you don't want to date or work unless and until you have a better handle on things. Smart. At the same time, though, you feel a need to do art and engage online, despite online interactions being a longstanding source of stress and trigger.
But it's not possible to have it both ways. You cannot control anyone but yourself. Ever. So if you don't like how something makes you feel, you are either going to have to give up the parts that hurt you, or accept that you are choosing to hurt yourself. Hurting yourself is bad.
I'm going to recommend two books to you, since you say you're a natural auto-didact (someone who is self-taught): 1) Set Boundaries, Find Peace, and 2) Six Pillars of Self-Esteem, in that order. Read and do the exercises.
Learning about these things won't fix everything, and of course has no impact on things like schizo-affective disorders, chromosomal issues, bipolarity, personality disorders, or autism. But perhaps it can help with the parts of the boundary/ interaction issues you've experienced that are related to childhood trauma, poor or abusive parenting, or other developmental derailers of that nature. Maybe there will be something that will help you feel better about yourself and even like and respect yourself more. Other people's opinions matter less and cause fewer unmanageable emotions when you respect yourself and learn how to assert yourself healthily.
You have challenges. But if nothing else, the last 24 hours has showed that you have, er, persistence. Emotional internet stuff isn't worth your time or energy - better to practice putting that energy and persistence into things that raise your mood/experience rather than lower it.
