What to do?

I just don't know what to do anymore. It seems as if the end of everything is happening. Ben and I aren't getting along. He is very disrespectful in the way he talks to me. He said"Fuck you" to me the other day. He screams at me that I am Crazy. He calls me names and he won't get off his butt. I can't reprimand him in any way or he goes off on me. If I mention his getting a license or a job he gets really shitty. I am totally sick of it. I have enough to deal with without having to deal with his shit!!
  The shop is closing in July. Dad is turning 91. Tyler is going to prison. Jesse is going back to California.  I am physically falling apart. I am completely financially devistated. And Ben won't even get a license.( I'm sure he has a social phobia and is probably depressed as well) So, I don't know what to do or where to start. The house is falling apart, literally. It needs a lot of work. I could have done most of the labor myself 4-5 years ago, but now I can's use a vaccuum.
  Things just don't seem to ever get better. And it's not in my mind.
