At a loss

Hi all, I'm on a six month waiting list for ankle fusion surgery due to arthritis. I've been told I will be non weight baring and recovery for 6 to 9 months. I work full time, live alone, have a mortgage and everything else that goes along as far as bills etc. I have no help and I really don't know what I'm going to do to manage all this! I've looked at the gov Web site but it's all so confusing. I'm really at a loss to be honest on where to start.
