Hey, I read that adrenal fatigue can cause all those symptoms. As for supplements, have you ever had any mineral hair analysis done? It really shows a good picture of what your body is missing. According to that, you would be prescribed supplements. Also, the truth about supplements is that if you are deficient, they will only start kicking in after about 2 years of taking them. You are taking too much vitamin C - I've heard that some people are too sensitive to it.
Also, medical marijuana might be smth to consider. Has been around for ages.
It seems like your body has lost the ability to relax. It is always in the state of alert - mental and physical. Sometimes it goes in that mode for years, and you would need a professional who addresses that.
