My Dad Refuses to Take Me to the Doctor

I have a disease that just makes me very sick when I have a flare up and my dad always makes me feel bad about having to take me to the doctor. I have a scab across my nose and inside of it so severe that it’s spreading and my dad gets mad about taking me to the doctors at all even when I get mad and I need a doctor. He tries to self diagnose and threatens me, and I’m so depressed over it and I have no energy to do anything anymore. He accuses me of not caring about him because I need to go to the doctor and I’m really tired of it I can’t take it anymore. Last time he refused to take me to the hospital and when I forced him to he didn’t talk to me for 3 days straight, after being 82lbs (normally 145lbs) and having a 7.2 hemoglobin, because he refused to take me to the hospital and he was mad at me and wouldn’t even hold my hand for the IV. I had to get 2 blood infusions, sat in the hospital for 28 days, then going to a psych ward because my dad accused me of being bulimic not because my body couldn’t hold any food. But my problem is I can’t go to the hospital with any other adult because my dads a legal guardian and I’m trapped… he won’t let me eat food right now and won’t even let me take any medication because he thinks it would help and then tells me the pain of me going to the hospital hurt worse than the pain I go through because of my disease.
