A girl I was "friends" with. She wasn't a great friend. But we were both really young, 15 years old, and I doubt she even knew if she was doing anything wrong and I believe that she has stopped a lot of her antics by now. She seems pretty great now, actually.
But, she manipulated me, took advantage of me, made me feel like crap, and forced me to do things I didn't want to do. She made me do all these favours for her and me being the sensitive, shy, socially awkward kid I was I didn't know how to say no and did everything she said and told me to do. She gossiped about her other friends, tried to get me to turn my back to them, and I'm pretty sure she gossiped about me too to other people. She went around the class once and humiliated me once. I went home and cried so much that night. Overall, she just made me feel like a piece of worthless shit and I don't even know if she knew what she was doing (I think she did sometimes on purpose, other times she may have just been being her and doing what she thoughts was okay and appropriate when it wasn't). Being 15 at the time, my self-esteem and self-worth was as fragile as glass. It was like being best friends with your bully. Again, I don't think she even that she was hurting me and it was my own fault for not speaking up for myself. She was also dealing with a lot of personal problems with her parents, their health, herself, and so on. So, I don't hate her. She was probably just acting that way to deal with her problems in a way she knew how. But I guess from all that, it still left emotional scars on me that even though I forgive and I don't hate her and if she ever wants someone to vent to like before I will be there for her, I refuse to talk to her anymore for any other reason, I refuse to be friends with her, I refuse to be as close with her as I once was. At the end of the day, she did teach me how to say no and stand up for myself; she helped me to grow up in that way and now I won't let anyone treat me like that ever again.
