Hi, I Am An 82 Yr. Old Female Who Has

Hi, I am an 82 yr. old female who has has CFS for 46 yrs. It grows worse with age and I am bedbound 90 % 0f the time. I sleep poorly even with clonazepam and have constant constipation. I have visited many doctors of all kinds and none will give me a diagnosis. I live in Hamilton, Ontario, Canada. Is there any doctore near here who can help me without prescribing antidepressants and a pscycologist?
