Bankruptcy 13 ? or Loan mod?

I Had a very bad year last year. My customer went out of business owing my small cont. company 100K. Needless to say I had to close my company and lose over 1 year income. I could not pay my mortgage for 4 MO now they served me forclose papers. I have a sub prime mortgage and they call offing me a deal cald a mortgage Mod. I dont owe any outher bills But the mortgage on my Home. They seem to be playing Games. Should I just go for a 13?
