Hi there and thanks for getting in touch with me,
It sounds like your school life is difficult at the moment and I can tell that you are very sad about what you are having to deal with. Everyone should be safe at school and it seems as though you trying to do the right things to stop these bullies.
Bullying is a behaviour that must not be tolerated and schools should have an anti-bullying policy that means by law they have to do something about bullying. I'm wondering if your mum and teacher know that the bullying is still happening? Do they know how sad it is making you feel?
There is a lot of helpful advice and information about bullying if you have a look at the ChildLine Explore section. It is also worth having a look at the ChildLine message boards to see what advice other young people have about bullying.
Have a think about talking to a ChildLine counsellor. They talk to lots of young people who are experiencing bullying. Together you can work out what support would help you. You can contact a ChildLine counsellor by calling 0800 1111 or logging in to the website for a 1-2-1 chat online.
I hope that this helps and that things can get better for you soon.
Take care
Sam
