I was in your spot until a week ago. I had to be out by Feb 1st but I was paralyzed with fear, anxiety and some heavy duty denial. I kept looking for a place to live but my landlord was holding all my money ($4000). To make a long story short, I looked up on line (cause I don't like to go out, particularly when I have to ask for help). All the services available in the county. I called one of the providers, Catholic Charities and they interceded with my landlord. Going to Catholic Charities was a huge trigger. I was forced up Catholic and now I avoid traditional Catholic services. Anyway, it did get a bit warm beneath the collar when I entered the church, but the folks were most helpful.
I guess what I want to say, if you need help breaking the sublet so that your Dad doesn't have to pay, check with one of the service providers. They might even have a list for short term lodging. Is there a neighboring town you could go to where you are not as known?
