I am sorry to read your health is in bad shape.
Try some herbal remedies. Here is a site of a herbalist that is excellent. Her name is Mary. You can also email her and explain your situation and she will advise you.

I consulted with her once about a physical problem that drs could not solve - and she sorted it. Worth trying! Good luck x
