I felt the same way you do. I looked at people who ate crappy etc have a perfectly healthy body and I wondered "why me"? Why can't I just eat normally or even have a glass of wine with dinner without getting sick.
Just know that there are a lot of people out here like you. I am sure you already know that not everything works for everyone. Because we are unique each person has to go through trial and error to find what works for them. Some people find their answer right away while others suffer for decades. Some people manifest differently. You can have 5 people with congested liver/gallbladder and they will all have different symptoms.
Basically what I am saying is please don't give up your quest to find the answer. It may not lie in Liver Flushes but the answer is out here somewhere. Please also don't give up on discovering your deep seated emotions. Anger sits in the liver/gallbladder. I can feel your (justified) anger from the last part of your post. But it will only poison you. I have been suffering from headaches for 35 years and JUST NOW discovered some wonderful books suggested by people here at Curezone that have helped me. I too eat great but have eczema, adrenal fatigue and am hypothyroid. Looking at all this depressed me to no end but I am determined to find the answer.
Here are a couple of books that might help:
The Emotion Code by Barry Nelson
We Are All In Shock by Stephanie Mines
It's ok to vent...now get on with learning more and getting better. Stay positive!!
