Frustration with obgyns

I am DONE having kids and have been since my youngest was born. Unfortunately the hospital he was born at did not offer tube tying during my c-section because it’s catholic owned. Since then I’ve tried various types of birth control mainly to lessen bleeding and cramps. Nothing has worked. In fact I have a nexplanon implant in my arm that has migrated out of place and it’s causing pain. Every time I go to the obgyn to discuss a hysterectomy they say my weight is an issue and just suggest an ablation. I have gone through enough band aid treatments to know that won’t work and will put me at risk if I do get pregnant. Which leads me back to my nexplanon. I have grown so sick and tired of doctors telling me I am overweight that I tried taking the damn thing out on my own. I failed obviously. How do I tell doctors not to get hung up on my weight so much to the point that I don’t want to get proper medical care?
