I haven't started Humaworm yet (just ordered some a few days ago), but I just wanted to say that whenever I do a cleanse of any kind, or have any sort of detox symptoms, I almost always get depression and or anxiety along with it. You sound like you are the same way...I would try to consider the down feelings as part of the detox process itself, and not worry too much! You are doing the right thing by trying to detox and that's all you can do. The herbs are very powerful and are definitley going to help!
Also, have you thought about getting a zapper? I am currently reading Hulda Clark's book "The Cure for all Diseases," and she strongly recommends zapping to help kill all this stuff.
Also, drink lots of water...your whole system will work better and you will pass more stuff faster if you are drinking tons of water!
