Could I have schizoid?

Hi everyone,

I'm just wondering if this could be schizoid personality disorder, or if I'm just an anti-social person.

When I was younger, I had friends...and in grades 9&10 I had my fair share of friends too. In grade 11 I had several breakdowns due to severe OCD and went to the hospital 5 times. Now I'm in grade 12, and since I've had my first breakdown I've basically only kept 2 close friends (the others are mere acquaintances), and I'm easily annoyed by them & my family and prefer to be alone most times. Whenever my friends call me I refuse to talk most of the time, and whenever they ask me to socialize I turn them down. It's not that I'm afraid to socialize, I just don't want to. :/ It makes me somewhat sad because I know there was a time when I used to like socializing, I just can't remember how that feels.

I don't like to do a lot of things...very few things make me happy. I'm sort of a flat and detached person. I like to joke around and stuff when I feel comfortable with my friends...so I still have my sense of humour, but a lot of the time I'm just like "Blah."

Also, I'm not sure if this is important but things annoy me easily, such as chewing, even if it's proper...and sometimes the sounds of peoples voices will bother me so much that I have to leave and go be by myself.

Does anyone have any insight? Thanks!
