I'm 12 years old and I'm constantly being bullied by my older sister. She is almost 16 and is both bigger and stranger than me and taks great delight in hurting me physically and emotionally, to the extend that as I write this I'm scared she is going to burst through my bedroom door and troment me about writing this. She has hated me since the day I was born (She slapped me when i was 3 days old) and I can't take it any more. My parents are divorced and I'm not going to my Dad's house any more because he used to bully me and tell me I was useless. I can get away form him, but not my sister. She likes to call me names, hit me and force me to let her get her own way. She often uses my pet (A giant african land snail, called Speedy) to make me do things, by threatening to kill him. I have told my mum but although she says she tries to stop her, she doesn't in the slightest. I can't fight back physically because she is stronger than me and if I do, she pretends to cry and tells mum a story she made up, usally about me hitting her for no reason, and mum wont punish her because I can't prove shes lying. I can outsmart her if I try, because I'm quite clever, but then she just resorts to violence. I could go on about all the other cruel stuff she does but that would take ages. I really need help. Please help me, because I can't take much more...
