I seriously do not know what it is wrong with me, but I (19m) doubt every single idea I have been able to think of for weeks or months now. I want to do so many things, but I instantly shoot down every single thing I try. Online career that I can slowly chip at and make work over time? "Why even try, it's gonna fail."

Hey, I will try to cook something new! "You're gonna screw it up."

Hey, I'll join this club at school! "Everyone will hate you, it is not worth your time."

I kind of wanna date someone. "Who the hell would want to even look at you?"

I do not know if this is a general mental health issue or not, I just wanted to see about it because I tend to have a lot of ADHD symptoms and I got a diagnosis from a doc confirming I have it. I do not know what to do but at this point I don't know if there is anything I can do. Any new idea or even anything where the chance of success is not a bare minimum of like 90% likely to succeed, I just abandon.

It could also be because I am extremely risk averse.
