Myself and my hubby

Husband with Parkinson's now for 15 years sleeps a lot. Only goes out when he wants to pop in the car or go shopping, which I go with him. He's declining, can't go out for a day trip anymore or going somewhere else. Husband's letter from nhs hospital states he's got anxiety and depression but if I offer to help him he tells me its all about me and it's none of my business. This really upsets me. He won't let me go to his consultant appointments with him. Thank you Debbie
