I feel awful about this

I am 24. In 2011 I moved away from home due to an emotionally abusive mom. In October 2014, I was forced to move back home as my living situation fell through and I had no where to go...now, being on a limited income, my only hope of escape is to put myself on a two yr waiting list for public housing...I have the papers filled out and have a meeting June 16 to start the process. One of my main reasons for moving out is so I can freely get medical care I need without fear of being punished and getting in trouble...yes....if I go to drs/dentist/urgent care/ER "without permission" my mom gets upset and punishes me..usually by taking away my car so I can't get to appts...I've been having wrist pain for a year and a half, I complained to my mom about it and she brushed it off as overuse pain from being on the computer...this didn't fly with me/..so two weeks ago I made an appt to see an ortho dr...I went behind moms back...he took an xray and diagnosed me with keinbocks disease which is a rare bone disease where the radius and ulna are different lengths...that puts pressure on a smaller hand bone and causes blood supply to it to begin to die....I'm currently in pt twice a week for 6 weeks and can't tell my mom...she thinks im taking a college course... In the past my moms also told me:

"You're only suicidal for attention"
"You never told us you were sexually assaulted in high school"(umm yes I did and was there when the school called...dear old mom denied that to
" you can't go to school for vet tech or nursing, the curriculum is too hard, you'll never succeed"
And there's many other words that hurt as well

I wish you the best. Unfortunately istitutions are very lacking in these fields that are crucial for the person.
I understand you perfectly, I passed -amongst other things- 6 months on the bed with the face on the pillow and I couldnt move one millimeter for the pain, now at my young age I have a lot of artificial teeth.

I can only say these persons dont have to live.
