If you go to the hospital, your parents will be forced to listen. And that would be a good thing for your situation. You will be heard, you will be kept safe, you will start getting treatment.
I went to the hospital once. It was a few years ago. But my mom drove me to the hospital and I believe I told them that I was feeling dangerously suicidal. They found a bed for me at a mental health center and I stayed for a week. We had groups, meetings with therapists and pdocs, plus some free time for journaling and taking us to the gym to run around.
Please keep staying safe. You can do this, you are strong.
