Hugs to you!! I am sorry you are going through such a tough time, and it does sound like a VERY tough time.
Does your school have a counselor? A school counselor is good at talking to parents so they see the need for counseling. Then they refer you to a private counselor outside the school. If you need help schedulig time to see the school counselor just go to your favorite teacher and ask for help.
I know--been there.
