I'm scared what should I do?

You poor thing! Reading this made me cry because i feel so sorry for you. DONT WORRY THOUGH talk to someone you trust at school on childline or your freinds. FIND HELP! if your mum puts you down ignor her and think to your self when she shouts at you it could be worse or comforting soothing thoughts. ( when i am angry i think of a cracking egg ) find something that makes you happy and do it often good luck ): be happy ;)
