my mom says she going to put me up for adoption and that she dont trust me no more, when i have done nothing to batray her trust. sure we never been close and never liked each other but i know matter how much i hate her for the emotional abuse and resent physical abuse she has cause me shes my mom, since school notice the split lip and black eye i had they asked me about it and im a terrible lier in the end i told them so they got social services involde which i didnt want cause i knew it just make things worst which it has. And it hurts knowing she dont want me cause all my life i have tryed to get her to aprove of me and accept me
