She knows some of what is going on but I don't what to tell her to much because I don't what to seem jealous and also I don't want to put my problems on her because she is going through a really tough time
I think it's great that you're trying to support your friend through her tough time. I definitely get where you're coming from in not wanting to tell her the full extent because of what she's going through. I'm wondering... if the situation was reversed, and she was being bullied, would you want her to tell you?
You deserve to be treated with respect and kindness, unconditionally. Is there a teacher or someone else you could talk to about this?
