Do I have a right to feel backstabbed?

Okay so we moved about 7 months ago from our home of a year & a half (temporary because my dad got his job new there but got promoted quick). Anyways I had a LOT of friends there..maybe more minions than friends but yeah. I was REALLY bitchy..I was a typical high school cliche but you know I had (still do) a good heart & always apologized for being a btchy. There was this chick who was 26 (I was 14), we got pretty close when I had just moved there. I found it a little odd that she didn't have any friends of her own but yeah she lived in an apartment with her mother. LOL anyways we bonded over our similar taste in t.v. shows. We kind of "ruled over" my street, like all the other kids feared us. She was MUCH MUCH MUCH more bitchy than me, she told people "Go kill yourself" "You wouldn't be here if your dad's rubber didn't break", really cruel harsh things. We were like "the best friends" until one day she stole my chanel bag, it was expensive & it was a present from my dad. I honestly said to her nicely "Hey I think you might have taken my bag because you were the only one besides me in my room yesterday." AND she was acting really suspicious the day she was there too, she was like "Oh I gotta go...I'm going to a movie." I was like "What movie?" & She was just like "oh ummmmmm the batman one!" (the dark knight). So then the next day she went around telling EVERYBODY that I was a TOTAL btch for accusing her & that I was way out of line and whatnot. I apologized to her like "I'm really sorry girlie, I didn't mean to hurt you, its just I didn't know who it could have been." She was like "Okay apology accepted." Then she STILL went talking trash about me calling me all these random things. Then is when I was a btch to HER, I was kinda out of line but she didn't bother stopping at any so why should I? I called her out of not having a job & mooching off her mother lol. OH YEAH and I called her out on how she ALWAYS copied me, I swear it was a little weird! NOBODY else would notice except me but she stole all my lines, all my interests & she would just act like she came up with them. Also I had this one really close friend Gabby, nobody had known her before I became her friend. I made her really popular but we got into a fight because I set her up with kind of a geeky guy but he was REALLY sweet & right her in league. So anyways she started taking sides with the 26 year old and this was all 3 days before we had to move. I was really glad to get outta there & I'm so over it but yesterday I talked to a friend of mine from there and she told me how they still remember me as the "btch of the street" & they always say "YOU'RE ACTING LIKE BROOKE!" when somebodys being a btch, like wtf? Seriously? Oh & they like idolize the 26, now 27 year old who apparently has taken my spot. She said that people call her the Brooke wannabe though sometimes & she desperately tries to be like me. I just feel slightly backstabbed because the people she named all used to kiss my like CRAZY, if they had a problem with me why didn't they confront me? Also Gabby is one of those people? I just wanna punch her face in because she was a total NOBODY before I became her friend & I ALWAYS had her back when the "popular girls" would pick on her, I even fought with my closest friends to defend her & this is what I get? GAH.
