People seem to just always hate me?

I am home from sc NYC and people hated me in HS. My sis said that it was because I was always messing up and getting into trouble, changing my appearance, walking around like I was the ****, and people thought I was a slut. Ppl like her much better then me b/c they compare her to me and she says they didn't like me at all. My sister always reminds me of my "ghetto" stage. Maybe thats what people will always think of me. I was just getting into alot of trouble then and speaking improper. But I was a cheerleader for 2 yrs then my Jr year a roumer went around that I was a slut and I got a ual reference nickname and I was cut Jr year and then made the team again in Sr Year and dated the Quaterback. I am a nice person but I wont let people be to me, I have made so many mistakes from saying i love you to too many people, getting arrested for shoplifting, lieing and I'm sure other things. I just want people to know I am not the confused girl I once was & that I am not a bad person
