As you are getting 1200/month, I assume this is SSDI? When were you granted disability? Did you have an attorney? Are you sure working is not going to impact your health? Working while receiving SSDI is a very gray area. I know SSA 'says' you can earn X amount, but the reality is they can interpret their own rules as they must. Lisa Gonzalez-Goetz, P.A (search youtube) says any work activity 'raises a redflag' and if you work 'you are now inviting Social Security back into your life'. She practices nationwide for over a decade. Reeves Law Firm, P.A. (on youtube) says 'man, so you asking how much money can I make, to supplement the money I get.. for not working?'. Think about it.
And SSA is totally indifferent to whether you starve or freeze to death.. They will enforce their rules, and I don't see this new administration as a bellwether of things getting better.
A local attorney here, during a seminar, said she use to do product liability cases. And she had no idea how complicated SSA law is, and still doesn't fully understand it (she does disability exclusively). SSA makes their own rules, interprets their own rules, and their processes are not transparent. Sorry if this comes across as paranoid, but I believe it to be accurate.
Nolo Press Guide to Disability is also a good resource, though the book changed significantly when a former SSA MD stopped writing them (IE different opinions).
As far as affording everything, if you haven't availed yourself of whatever social services are in your area (either seeing a case worker or doing it online, if possible). You would probably qualify for LHEAP (utility assistance).
Since you are disabled you also qualify for special deductions to boost your FoodStamp allotment. My caseworker here didn't even know these rules. I had to take it to a supervisor to have my benefit calculated properly.

All medical out of pocket is deductible, dollar for dollar, along with transportation to and from those appointments, accommodations (if required), etc. Also if you take any medications, and don't have RX coverage, you can use GoodRx.com or check the manufacturer of the drug. Some drug manufactures have patient assistance programs that go directly through the company.
Hope that helps.
