I am sorry to hear about your experience, but take some courage there are many who are in the same situation. It is hard.
I would suggest looking into Dr,. Galland (leo) info on the internet concerning treatement of Chronic Fatiguers in which he suggests looking at the GI tract specifically parasites as the origins on many degenerative diseases.
But he makes a point in which he talks about parasite testing... he got to the point that it is not even worth trying to diagnose parasites due to the inaccuracy and frustration. He just treats them. I have posted his info on another post.
I am treating myself using some Indian principles treating both worm and protozoan but treatment time is a minimum of 3 months. I think the duration is critically important. No 2 week protocol is going to clear a long term infection.
