Please help I want to commit suicide?

Talk to your school counselor and ask her to refer you to a licensed mental health therapist. In the meantime try to stop expecting your parents to completely understand where you are coming from. I went through some sexual trauma at an early age as well and nobody in my family wanted to acknowledge it. So now at 23 years old I have come to accept it and I harldy have anything to do with anyone in my family.
