do i have a personality disorder ?

hi ... i'm Emily ! i'm 16 years old , i have a serious problem that i'd like to share ! i hate going to the therapist , and i think i have personality disorder !! i'm known as cold , aloof , unemotional and antisocial . As i don't communicate with others , i have no friends as i always regard others as better than me where every girl in my school wants to be my friend because they think i'm attractive and pretty ! i'm known as being a mean person , i always hurt other people ( even people i don't know ) in a certain way ! i don't want any friends as i like being on my own all the time , i have weird habits and interests !  i'm always calm and silent ! if i were in a fight , i stay calm but in the end i end up beating up the enemy or hitting him , it's weird for a girl to use physical strength but i practice a lot of sports ! like in class while the girls and boys are talking in the break i'll be the one sitting in the corner in silence , observing every student's acts ! in class i always sleep or day dream but in the exam day , the teachers become surprised when they see that i got A+ , because i'm always not paying attention in class ! but i do study a bit in home ! i'm a smart person as i can read people's mind in somehow , like if i stayed with a person for 1 week , i'll know the exact way of his thinking ! and i still have imaginary friends who are ALWAYS with me , in class , home , everywhere .... i talk to them and tell them all my secrets and they talk to me ! they usually talk to me in class and the teacher makes me go to the ditention for talking to myself in class ! i hold revenges and grudges on people who hurt me , even if they said something they didn't mean to say , i have to hurt them in the exact same way ! people can't understand me !! sometimes i can't understand myself ! my life is weird , not normal ! and a little help will be good !  thanks ....

It seems you are getting help...hating your therapist is part of the picture, not a real drawback, but something to talk about with your therapist...you described your outer behavior well, but it is your inner life,....you insecurities and sensitivities that have to be understood in a new way to allow you to change your behavior, and enjoy these wonderful years much more.
