I believe that you can work earning up to $800 a month without losing the insurance payments. Maybe doing that can be a medium term goal.

As a short term goal, I would choose volunteering. Now is the season so, say, American Red Cross thrift shops might look for volunteers. On a more long term basis, there are other opportunities if you look around. Some of library volunteering do not involve customer contact. Some non-profits may need data entry volunteers - again, no customer contact.

You will regain some stamina from volunteering, put the volunteering on your resume, and armed with both, look for a part time job. If you make $500 a month, that would make a big difference already.
