Sorry about your situation and your low feelings Sloegin, nice name by the way! I agree with others, if big problems like the washer arise, they need to be fixed professionally, otherwise they may re-occur.
Write a to-do list of all the big and little tasks that need doing, leave it lieing around, your husband may see the scope of work that needs doing and realise the house isn't manageable. I find if I have a list and cross a task off, they is a feeling of achievement. I also found my self doing extra things, not on the list, so I would add them just so I could cross them off, daft yes, but gives you a buzz.
You unfortunately say your husband's health won't improve, I am sorry for that. Maybe the little jobs you get done on the house will all help improve the saleability of the house, when it is right for you. So see these tasks, as a means to eventually moving to a place that suits you.
I would speak to your neighbours, and ask if they know of a local lad, who is reliable and can help out with the garden, windows, and other more physical jobs. Then you will have a nice garden you can take a break in, with a glass of sloegin.
Most importantly, take care of yourself, see the GP, and make sure you talk about you at the appointment, not your husband.
Take care
