I am 63 and my normal weight is around 135 I am 5Ƈ" and now weigh 220

Check with your insurance company. They may have free courses or exercise classes that you can take.
Most of the "lose weight for free" programs are a scam. There are a few legit ones, that are testing new drugs and if you have any medical conditions it prohibits you from becoming a test case.
You can also check with your state department of health as they know of free programs.
When is your next visit with your doctor? Give his/her office a call and see if they can help you. Since they already know your limitations is should be easy for them to help out.
There are so many resources out there that can help you.
