It could be, when I was in high school I was so mean to my friends at times. I would get so irritated and they would be upset with me. I didn't want to see any of them or hang out with any of them. I really didn't talk to anyone by my Junior year. I finally went to a doctor and it was depression. Which upset me even more, but now looking back on it, I can see why I was always so irritated and anti-social.
Some people will rub you the wrong way, my sisters did since we were always around each other, but now that I know I am depressed at least I can figure out why I am so irritated with people instead of just being angry all the time.
Go and see a doctor, what's the worst that could happen? You never know, it might help and you will start to want to talk to people again!
