Father banning surgery because I'm on his insurance

Location: West Virginia

I (20f) was supposed to get surgery to remove my fallopian tubes and surgically insert an IUD. I don't and have never wanted kids and have had horribly heavy, debilitatingly painful periods for 10 years now. I have been on nearly every form of birth control to try to fix it and it's impossible for me to get an IUD the normal way. This is literally my last option.

Despite my better judgment, I informed my parents and they were not happy. A major fight broke out and ended with my father demanding the talk to my doctor/surgeon the night before my surgery. Against her advice, he said that I am not allowed to receive the surgery to remove my tubes, saying he has the ultimate authority because I am on his insurance plan.

The surgery was canceled, I cannot drive myself, and they threaded to slash my grandmas tires if she took me. I'm not sure of what to do.

I have no job, I'm going off to college in 80 days an hour and a half away where I can get student health insurance, but that's +$3,000 I do not have. Plus the cost of the surgery its self. It doesn't help that my dad is the one offering to pay and without him I would not be able to go at all.

What I am especially worried about is if I do manage to get the IUD and it stops working like all the other birth controls I've been on. The ONLY option I will have left if removing my uterus and tubes to stop the never ending bleeding I have been experiencing for over 6 months now. Something he has already stated he will never allow short of getting cancer. Insurance did approve the surgery initially, does my dad really have the authority to stop this? I do live with him so getting the surgery somehow and hiding it would be impossible. What do I do?
