I also understand the frustration, I'm discovering a few problems myself with cleansing. But what I have learned about my body and how it works is invaluable. I am sure that you have also gained knowledge of yourself through the trials and tribulations, this is worth it's weight in gold. Use what you have learned, follow your gut feelings. The fact that you have posted means you dont want to give up - you will know what is right for you, no matter what anyone else is doing.
Also, there is such a thing as not wanting to get well for some subconscious reason, or a belief that you cant get well or that you dont deserve good health. Dont shoot me down in flames, cause I have shocked myself a couple of times when I discovered a few of my own beliefs! Ok, so it's not working on the physical level, perhaps its time to do some cleansing on the subconscious level?
