I’ve been doing yearly detoxes for a few years (before starting the candida treatment last month), and I pretty much always have at least one or two days where I feel emotionally terrible. Sort of panicky, or really sad, or really agitated, angry, etc. I agree with Emsmith. While I don’t have hard science to back this up, based on my experience, I think the body is metabolizing stress hormones that we haven’t had time to process yet, and to get them out of your body, you end up experiencing the emotions associated with them.
Definitely support your liver and kidneys. After years of neglect/abuse, they need help in order to help you.
