Meg,
It is so good to see you post. I was wondering how you have been.
I would check into staying on your dad's insurance as a disabled dependant and see what happens. If you had symptoms and difficuty with maintaining school, job, since you were under 18, or high school ? Maybe 21 then you should try to apply for Soc sec and assistance to ave coverage.

I had two children maintained as adults on step dads insurance because their disability was prior to 18...Even though they tried to work.
You need to see if this new symptoms is related to something like RSD, fybromyalgia or auto immunine, but it will be difficult to take care of yourself without insurance.
Ask your Dad o find out how to have you kept on for disability.....

Then apply everywhere for anything to keep you going while you find out health wise how to get better.
Hugs
