Sounds alot like what I had going about 15 years ago. Alot of stress plus I was also drinking alot (very bad marriage). It really put a drain on my system, then I suddenly started getting so constipated it even hurt to sit down. I was not educated about natural health practices until this started up. A doctor diagnosed me with candida. I now believe the stress just totally compromised my digestive system. One thing that really, really affected me badly was MSG. Talk about feeling like a space cadet! It made my brain fuzzy for days at a time, plus I felt like I had the worst case of flu ever. You know the kind that hurts down to the core of every bone in your body. It took some time and many set backs to find the culprit. But of course with a compromised digestive system I was not digesting anything very well. I stuck out the candida diet for almost 10 years. Lost alot of weight, but I looked horrible. I was eating mostly raw vegetables but I think that was too hard on my system. I hope you are successful in your healing path sooner than I was. Good luck!
