You really must put Philip's and your health as a number one priority, Elizabeth and you cannot continue to work at the rate of knots and be a full-time carer and provider.
I have a house husband, and can fully recommend it. He is a great chef, our clothes are washed and ironed beautifully, and I have a garden to be envied. More importantly I have a happy hubby, and a terrific support mechanism which enables me to work that hours that I do.
Although my husband (touch wood) enjoys very good health, I am sure that Philip would adapt and find a lot of things to fill his day, and you would be less stressed if you were not worrying about him constantly. Does he have any hobbies?
