Just give up on people.
Focus on improving your skills so much that you won't need them ever again.
Brain damage, mental illness, and genetics. You don't just become one.
There's also schizoid I guess. Same thing though, so if you're hoping to no longer want interaction then good fucking luck, my friend.
4chan is the extent of my social interaction needs and I don't really need it since I get banned for bullshit all the time and don't even care.
Although I probably really do have a personality disorder.
Today I fulfilled my social needs by biking to mcdonald's, calling a rude driver a motherfucker, fuck you, and flicking them off, then ordering breakfast and a coffee at 10pm.
I don't know if I have a personality disorder, but considering this isn't unusual for me I probably do.
