Hi Valerie - Your Trich was not completely cured years ago, even though it seems like it was since the symptoms went away. I know that this idea is hard to understand and accept at first because it contradicts everything we've been taught about disease and curing it. You might want to do more reading on the topic.
As far as what you should do, I agree with the recommendations in the previous post. Chris knows a lot about fasting, and can guide you as you do more of it.
