Do I have the Schzoid personality disorder?

I tend to work alone and abstain myself from group activity. I am not narcissistic or superior in any way, I just enjoy working and sitting alone having my own personal space. I, however, feel irritated when I'm on the bus, because there are so many people. For some reason, I hate people and usually feel angry and annoyed around them. Don't ask me about overly-social people, I think they're f"ckheads and are too emotional. My parents and family constantly emphasize on how cold and emotionless I am but in reality, I just want my own space. Teachers constantly write on my report that I tend to be withdrawn with my clmates. Also, 100% of my time since high school, I sat alone by myself and get really pissed at overly social b****** or b********. It usually results in arguments and fights if they ried to be friends with me, because I usually yell at them. I spend most of my time alone at home, studying, playing with my pet chicken or play piano.
