I am a young man who went through something very similar to what you are going through. It's now been 1.5 years since I had my mercury fillings removed (12 in total) and started chelating with DMSA/ALA/chlorella/vitamin C and later DMPS (brand name "MercOut"). To put it simply, I went from one foot in the grave to being 95% recovered. That's why I don't post much anymore.
I recommend that you do a search under my name and read my old posts. Hopefully you will find something there in my trial and error that will help guide you in getting better.
