Some more ideas:
A local Senior Center may have or know of additional services and resources in your community.
Also, might want to contact the National Council on Aging for resources and ideas http://www.ncoa.org/
Utility companies sometimes have special rates for low-income or financial hardship situations.
Medical bills: Most doctors, hospitals, etc., have some kind of program or help for those struggling financially. Ask about charity programs, payment plans, and applications for financial assistance.
Prescriptions: Patient Assistance Programs are available for many prescription medications. Check out the Partnership for Prescription Assistance http://pparx.org/
I hope this helps...take care,
