You tell your parents the truth.
Look, kid, I feel for you, but I can't magically make you feel better. If you want something to change, you're going to have to take matters into your own hands. Talk to your parents. Call your doctor. Get help now. Don't make excuses. Shooting down every suggestion in this topic sure as hell isn't going to make the bad thoughts go away.
This is not me getting mad, this is me trying to get through to you.
