Well, not meant to offend with this at all so don’t take it the wrong way please, but you do seem to act like you know better than professionals, and that can be a problem for you on the long run, a real obstacle for recovery.
Talk therapy is very benefitial. I’ve learned not to believe I’m a bad person because of my intrusive thoughts, for example. Learned how to deal with them when they come, how to react to them. Just from moderating you, I can tell you would benefit from it.
Why compare yourself to a neurotypical? And even comparing yourself, they do that for a living, they’ve seen really bad situations.
If you were open to others helping you, you probably would be in a better shape.
Nothing is fixed in stone. For the first year after my hospitalization I hardly spoke, couldn’t form sentences and prefered to stay quiet. That passed with training myself to talk, first about superfluos things, then off to meaningful. If you just resign yourself to learned helplessness you won’t get out of the gutter.
Before coming to terms with my mental illness, I did a lot of bad things, I had a lot of bad thoughts and I changed. So I don’t think you should wallow in self pitty and refuse treatment because you think others wouldn’t understand, I think you would be surprised on how well mental health professionals understand our issues, and we’re there to educate them further too. It’s a win-win situation.
Of course there are bad professionals, but that’s why we learn how to pick them, if one doesn’t help, others might.
Don’t give up on your recovery because of stubborness.
