No health insurance but lots of issues

Hello I’m 17 and my family doesn’t have health insurance. We aren’t super well off and only my mom works. Her job offers something called a hospital amenity plan which I don’t know much about. I have a sibling too however just me alone these are the thing I need to go for
- colonoscopy
- diabetes
- vertigo/anemia?
- extreme stomach pain which is why I need the colonoscopy because I might have Crohn’s disease
And i’m not sure if dental is separate, but I also really need to go through that too. I have cavities between every single one of my teeth. As well as mental health like therapy. All of us are mentally ill and I desperately need treatment.

And that’s just me alone. It doesn’t look like my dad‘s gonna get a job anytime soon and me and my brother are starting college so that’s a lot of money plus I need a car too. Idk how any of this adult money stuff even works. Is there anything else I can do? I used to be a competitive athlete however I stopped competing due to pain. I’m bed bound on some days.
