I'm sorry you're going through all of this. Yes, you can have moments of hope or numbness from depression.

Depending on where you live, you might be able to get assistance if you do wind up being disabled. I know here, Section 8 does or used to help first time disabled home buyers pay the down payment. There must be some sort of assistance out there to help you keep your house if you can't work due to a disability.

I would suggest to start researching some different government assistance programs or grants. Maybe even contact an advocate. You could even contact your senator, congressman, governor, or mayor. You might even try contacting your local crisis line to see if maybe they have resources. And if you know of any crisis houses near by, they usually have a ton of resources for housing (though most probably won't help...but it may).
