What should I do with my medical conditions?

Hey everyone. I've been living a few years with some conditions now. One in particular causes me to have heartburn each morning and make me ultra sensitive and close to throw up. I always need to concentrate several hours to not throw up and it drains my energy. Not to mention the stomach issues it causes as well. Multiple doctors know about it for years but just give me stuff that doesn't help and they just try to find an easy and fast solution instead of actually looking into it and help.

I don't want to kill my body with cheap medication.

What should I do and does anyone have experience with similar stuff?
