Hi Rebecca
Such a sad time for you right now. Having your parents close by must be a real help and comfort to you. I can't really add anything to what has already been said but understand a little of what you say having been through a divorce in similar circumstances myself.
John's advice to hold fire on a divorce is sound, don't rush into making long term decisions right now. Here's the link for
Disability Living Allowance (DLA) . It is available to people who need help or supervision with personal care or have walking difficulties, whether in employment or not. I don't know whether you will qualify for this, but am sure NRAS will be able to advise you of what is available. Things have changed completely since I was at work!
Hope things improve for you soon. Please try to be positive and keep posting
