I'm only familiar with Frederick Community Action Agency
not sure if that's too far for you. They provide food, shelter, medical care, housing, and other forms of assistance to families and individuals that are low-income or homeless.
I'm glad you've been able to see doctors. I had a hard time at first finding a doctor to treat and diagnose my fibro.
Do find out what the risks are for taking predisone long-term. I was taking trazodone and something else(can't remember) and I developed spasms afters being on it for 2+ years. As long as you know the risks and are willing to deal with them.
Hoping you're able to get the help you need ASAP
