PLEASE Anna, talk to your counselor at school. That's what they're there for, besides talking about school issues. They will talk to you about personal issues too. But please talk to him/her. You MUST talk to an adult that is trained in this type thing. And if you won't talk to your parents, the only other choice you have is your school counselor.
What you really need is a therapist -- but since you won't talk to your parents, talk to your counselor at school. And please make sure you do because you have to talk to someone. It's very important. And please let me know what happens, okay? You can private message me or something if you want to. God bless and please take care. Hugs, Lee
