I too have been where you are. I have lost my home, 2 cars and my dignity over my disabilities. I had to live in an apartment complex for 3.5 years where there were drug busts, ODs and other assorted reasons to call the cops. For a short time, my husband and I lived off of my SSDI and LTD benefits only. We had no car for a short time as well. So, I know about the feelings you describe.
I was very lucky and got SSDI on my first try. But it is a difficult row to hoe especially when you are hurting.
So welcome.
