Stay strong and think positive, I know it's hard to do at times. I'm in my 30's and I've had this disorder for over 20 years. It can make you crazy. There are so many things happening on the boards now, I feel like many of us are going to get the help we need. I think I have a problem with candida also, I took odor cleanse/Champex for a short time and it made matters worse. In addition to that I suspect I have TMAU, not sure how it all ties in.
There was someone on this board months ago that described his problem the same as you have. I think his user name was "hadenuff" not sure about the spelling. Have you looked over his old posts? He was able to overcome his disorder.
