Hello there
Thanks for writing to me about the diffculties you've been having.
I'm sorry to read that you are being bullied at school and that your teacher doesn't believe you. I can see why that might make it difficult to do your school work.
It's great that you are managing to stay in the top group despite the problems you've been having.
I'm a bit worried though about what you said about being locked in the head master's office without anything to eat.This is not acceptable behaviour by a person in a position of trust, whatever the reason.
How about talking to your teacher about what's been going on you said she is nice. If that doesn't feel ok, is there another teacher or adult you could talk to? Maybe someone at home? Have a think about telling someone.
If you prefer you could phone and speak to a ChildLine counsellor on 0800 1111 or login and have a 1-2-1chat.
You've been really brave to tell me about what's been happening so please come and make contact with ChildLine.
Take care
Sam
