What should i do if I might be experiencing medical neglect via my mother?

Im not quite sure this belongs on here but this is the best i could find. I don't know if i would even count my mother as narcissistic, but she has bpd or bipolar idk which is which, but the one with manic episodes. Anyways, Im 14 and I randomly thought of medical neglect of one of the things that may be happening to me.

1. I haven't been to the dentist for 3-5 yrs? I don't quite remember how long ago my last visit was; and I have several visible cavities on my lower teeth(they're not in constant pain but hurt sometimes) Ive asked her to take me to the dentist several times over the years and she's basically just said not now.

2. I suspect that I have something like low iron or anemia, Ive even researched POTS a little; basically when i stand I lose my vision for a bit and get dizzy, and ive fallen/had to grab onto something to not fall. I have told my mother several times about this, and Ive asked one doctor and he said to exercise more, and she always dismisses my worries about my health.

   1. idk if mental health counts but yeah. Im dyslexic, not diagnosed, ive told her, mention how i struggle a lot actually, and she has done nothing to try and get me diagnosed or help.
   2. ive struggled w/ depression, sh, and su1cidal thoughts + suc1de since i was 11. She knows about the sh, she's seen scars, did nothing except yell at me and shove her own wrist in my face and take me to urgent care just in case case i could've had tetanus. im not sure if she knows about the su1cide and depression.

Just wanna ask for advice for what i should do, if you want to know more details about anything just ask, I'll be ok to answer questions if it helps.
