Wow, I must admit I am surprised at the amount of people like this. I have nothing wrong with me, aside from laziness and the complete lack of care for alot of things that most people stress out over.
I'm fine in social situations. The biggest thing is I can never relate to anything they have to say, and I don't have much in common with most people, so outside of good friends, theres not a lot for me to talk about. Even then, they only listen to humor me. Nobody really gives 2 shits about how the TSL3 is going or how the new episode of Dr. Who was, etc.
I just wanna say, just because you guys don't like socializing with other people, doesn't mean you have social anxiety. It just means you have an introverted personality.
Although I've never been professionally diagnosed, I am fairly certain I have schizoid personality disorder.
