Hi, Rincad, and welcome to Psych Central! Although some of us have diagnosed personality disorders, we could only guess what's happening with you, since we're not qualified to diagnose. Sometimes people perceive themselves as having some disorder since many people have one or two, at least, such symptoms.

The only way to know for sure is to get evaluated by a mental health professional. Plus, I'm thinking someone needs to be 18 to be officially diagnosed, since personality can be changing during the teen years.

I suggest you talk to a school counselor, since your asking indicates you are concerned. If these pervasive ways of acting are dealt with earlier, then I think the likelihood of getting out of them is higher. Would you consider therapy? Your life will be happier as a result. (I was able to overcome borderline personality disorder.)

Again, welcome! Make yourself at home here.
