So just wanted to add my two cents in and maybe some more reflection will help you find the answers you need. If your adrenal are worn out that starts effecting all sorts of systems in the body in crazy ways. Then putting more anxiety or any kind of stress can be too much. Stress comes in all forms even walking across a room and sitting down requires energy and if your system is weak this can be too much for it.
Also my friends symptoms of AF were very different than mine. Her first big collapse came when she started having tachycardia. Her heart would go crazy at the slightest things like eating, she had to go up stairs very very slowly. Even getting into the water like in a lake or a swimming pool would send her heart beating so fast. Just the pressure of the water on her body would do that.
If your doing liver flushes, detoxes, parasite cleanses or even drastically changing your diet adds on stress to your body because your body has to work harder to process all that stuff. I know some do get relief with Liver Flushes or the other things but if you read through a lot of the Liver Flush Forum posts you will find people that Liver Flushes have caused adrenal crashes. I have actual done all of these things and although I did get a little benefit from them they did nothing to help heal my adrenals.
Resting and relaxing seem to be the biggest factors in healing for me.
