Hi Anne. She may be able to get help with medications. Most drug manufacturers have patient assistance programs for people who are uninsured or whose insurance does not cover the meds. They provide the meds at low or no cost. These programs do work.
I am not sure what programs may be avaiable to help with the costs of doctor appointments and other medical expenses. Maybe try Googling "financial help for medical expenses" and see what you can find out.
I hope she can get the help she needs.
