Feel alone - trying to be strong for husband but I have no-one to talk to about my feelings

I am trying to be strong for my husband he has just had major surgery for nasal cancer he is so poorly and weak. I tried to see my GP but couldn't get appointment only on phone. I am trying to look after him but need to work to pay bills, also I have no one to talk to about my feelings, I want to take proper care of him as he is my world

Any advice please
