It's really important you can talk to someone. If you're at school, could you visit a counselor or go to the school nurse? Most schools do offer a counseling service and I'd really recommend that you go and try and get some professional help here. As for the physical symptoms you've described - again, if your mum won't help you, go to the school nurse. She can help you and recommend any other options that you have.

I'm sorry if that wasn't of much help - you didn't give me very much to go on emotionally. As I said, try and talk to somebody. It's clear that your mum's treatment towards you has had a massive impact on how you're feeling, and as she doesn't talk to you, you bottle everything up inside and close yourself off from the world.

Good luck :)
