Bipolar Or Paranoid?

Here it goes when I was in high school I was accused of stealing, when my teacher who asked me to take her book from the teachers' common room lost her money, since then I was the black sheep the discpline master seems to hate me and I seems to be the target from time to time, when I was younger, in primary school, I ran in a race, I was a reserved runner but when the actual runner was sick I had to cover her, the trophy was given to her instead, when I wanted to join in the school dance the teacher said it was too late I waited the next year and when I asked her early next year she said she had already made her pick. Please don't get me wrong I have nothing against teachers in fact I love teachers and I'm still keep in contact with one of my favorite teacher but just now I had this flashback, this happened to me from time to time and everything I'm annoyed that these things happened and I am frustrated that I can't get these things out of my head am I paranoid or bipolar? Can anyone tell me thank you...
