People can actually go to a doctor/therapist (or many) and still resist the actual treatment because they don't like it. College students get suspended from my university every month for angry outbursts, psychotic episodes and extreme depression. Most of the time it is because the student willingly decided to not take their prescribed medication and/or attend therapy sessions. This is resisting treatment. I honestly don't know if the OP is trying to fool himself in the same way or not -- but I thought I would suggest it for his own consideration.
Something about ASD is those people lack a lot of the mental controls and emotional controls the rest of have. But more importantly they do not have the ablilty to read social cues like sarcasm. Or read people faces and emotions.
On top of that lets look at a normal person. On a normal person when some one close (best friend) says something hurtful it cuts deep because emotional walls to protect ones heart is not in place to stop it. I know it is that way for me. Now take some one with ASD who lacks the ability to understand sarcasm or have the same emotional control it strikes really deep and sets them off.
Best way is to try to have a way to dump that frustrations My way when I feel my emotional losing control is I pull away from the world and hide playing my 360.
