Agreed, you need to do a parsite cleanse, and Humaworm's great. You should start with a Colon Cleanse though (Humaworm also sells a Colon Cleanse porduct on his website for your convenience, you can take both at the same time), and also do a liver/kidney cleanse. Talk to Dr. Dennis Hardy on his forum on what herbs you should take for cleansing the liver and kidneys, be sure to tell him you have Chronic Fatitgue.
A raw diet would be good, I'd start off with simpler, easy to digest foods like fruit and raw salads topped with extra virgin olive oil and whatnot for the most part, until you start to feel better and cleanse your colon. The you can try some of the fancier raw recipes (many of these contain nuts, with can be hard to digest).
Buy a juicer, it'll be the best decision you make for your health :) Juice at least 4 cups of fresh juice everyday. It'll help you to get your energy back and cleanse.
