Sick Hubby

I don't know what is worse, a sick husband or a sick dog...or both! Here I am with a hurt knee, trying to stay off of it the best I can nursing a sick husband and a post-op dog! I am feeling a little run down right now. Any advice on caring for a sick husband who only seems able to think of himself (not meant in a mean way, but meant in a what all women know about men way).
