I'm new here, but am familiar with your symptoms. The western medical establishment called mine fibromyalgia, which I just believe to be a state of unhealthiness within the body that can probably be cured through cleanses, etc.
I haven't done the parasite cleanse yet BUT I do know that at one point when I had candida overgrowth I had ALL your symptoms. You could have both candida AND parasites. I cleansed myself of the candida years ago and feel so much better, particularly emotionally. I cannot eat white flour, sugar, dairy or yeast products now but it's worth it not to feel like I did before.
I'd go through The Master Cleanse if I were you. Click at the top of the page where it says Dr. Clark. The page it pulls up will show you the cleanses in the order which you need to do them. Let us know how you feel.
