Do I see a psychologist that deals only with cancer patients or any psychologist?

@Harley B thanks. I think you might be on the right track with the exercise psychologist  Probably the right psychologist is the right one. Actually admitting I need help is hard. I can continue as I am ..
. Well energy will return eventually. Wont it?..... However if there are tools and people out there that can help then not even trying is silly. I honestly thought well a year of treatment is over and I would just bounce back.....mmmmm
