yes.
I had this problem. I moved 1,000 miles away, and cited similar reasons. I had a history of the things you spoke of in school as well and they affected me my whole life. I always have an inferiority complex to this day and I always feel like people around me are judging me.
I learned most of it is internal. There are legitimately people who dislike me for various reasons, but most of it, I learned, I put on myself. It's as if I liked to convince myself everyone hates me and thinks I'm weird, and that simply isn't true.
