Hi Hope,
I may have missed this but do you have any drug insurance coverage?
I manage medications for a disabled family member on Medicaid. Some medications are not covered, not on formulary.
Sometimes there is a program directly through the manufacturer to help people with limited income like my relative. Maybe try to look up the drug and manufacturer online to check.

Hope, I wish you the best. I think you've made some really good progress. It's just hard sometimes to keep going, I know. Sending hugs.
