The advise already given is good. I would like to add some though. The following is not medical advice but comes from experience.
What you have may possibly be a severe candida infection along with other parasites. The road to fix this is long and difficult.
Get a good zapper similar to ParaZapper CCa with copper paddles and copper foot pads. The use of this can help speed your results.
Fast for 24 hours, drinking only good clean ozonated water, not chlorinated. Drink at least 6 to 8 glasses during this period. This will seriously weaken the candida. Definitely do not eat any wheat, starches, sugar, etc which is what candida thrives on.
Zapping with both copper paddles and footpads extensively at the end of the 24 hours will help eliminate a lot more of the candida.
Following this with an Epsom Salts flush will help force it all out. Follow this with 4 alfalfa tablets taken with 6 oz of water.
Starting right after flushing, I would eat 1 tablespoon of good yogurt every 15 minutes for 2 hours then take 1 tablespoon every hour for four more hours after that.
