Self diagnosis for adhd and asd is a pretty strong predictor for an actual diagnosis. Also self help is a huge part of therapy/management anyway, so why not do some self help and acceptance? theres no 'cure ’ to either. making it your personality and an excuse for being an asshole is a symptom of assholism. That, however, is really hard to self diagnose due to the nature of being an unreflected selfish manbaby egomaniac.
