I've been reading the posts by both Kaya and LindaV, and it breaks my heart. At this stage of our lives, we all deserve the stability of a permanent roof over our heads, food in our bellies, a peaceful life and medical care/free meds.
I came so close to being homeless myself that it scares the daylights out of me when it's happening or about to happen to somebody I "know" in cyberspace.
Another thing..."senior" living apartments? Even in my tiny hometown in the UP of Michigan there are apartments for seniors, and the age requirement is only 55. There's also a section of the complex for special needs residents (no age requirement) who are able to live without supervision. Some of them are physically disabled, some of limited but functional intelligence.
Those apartments are NICE! Small but nice, and there are even garages available for those who want to/can afford an extra $25/month. The rent is income-based so there are residents who pay nothing at all, some who pay just a small portion and some whose income is fine and pay the full market-rate rent.
Also, are you aware of SSI? It's Supplemental Security Income from the Social Security Administration, and even if you're not eligible for SS yet, you might qualify. If your income is less than whatever is the threshold (I don't know what the amount is), you can qualify for some actual $$ help and being on SSI also qualifies you for food stamps, Medicaid, rental assistance, often phone service, assistance with heat/water/electricity.
Also, once you started receiving Social Security, if your benefits are small enough that you still won't meet the income threshold, it's possible to qualify for SSI in addition to your SS benefit. If you don't also qualify for SSI, you can still qualify for food stamps, Medicaid (before you turn 65 and change to Medicare), rental assistance, phone service, help with utilities.
I only know about this stuff because DH worked for the State of Michigan in what was called then The Family Assistance Agency. His job was to help people to get jobs, get educated for jobs, find additional income/assistance that they were eligible to receive. Many of those people were people with families, but there were a lot of them who were older people with no resources and not able to work.
Of course, except for SSI, help available varies by state.
