I have a dilemma

I don't know what to do. Since my husband's arrest I've been living with my sister and brother in law in the trailer that my husband and I bought. I have turned ownership of it over to them. I don't work really. I'm trying to get ssi or ssdi. I have some health issues. I have been taking care of my parents. They are in their 80's. My Dad stopped driving last March, so I drive them to the store and doctors appointments. I'm just getting paid by the state for their care. It's not much.
The problem is my sister came to me last weekend and told me tat they're approved for a mortgage and will be looking for a house. They say they might have one by March. I can't stay in the trailer. I physically can't keep up the maintenance on the trailer and I have been told by the management of the trailer court that my husband can't live here when he comes home. There was a little publicity around his arrest. They don't want a SO living here. I have my name in for section 8. It may take a little while to get a voucher. I feel homeless and trapped. I'm dealing with my husband in prison and my daughter's passing. I haven't slept in a bed in over a year. I sleep in a recliner. I have a lot of anxiety along with depression. 
I don't know what to do. I can't hurry section 8 and I can't hurry social security. What I make taking care of my parents won't be enough to gat a place to live and when my husband comes home I'll have to get off section 8.
I'm kind of between a rock and a hard place. My next problem is to downsize. But that's another entry.
