Health and symptoms : listener question

I'm loving the Energy Course that we are doing at the moment.  Day 4 video WOW - I found everything you said just seemed to almost flow through me, making complete and utter sense.  

I have a question for you - one area I seem to struggle and get caught up in still, is my health (believed to be caused by high histamine levels).  My mind/body system still wants to resist the energetic flow of Intelligence/life and shift back to a Reality of fear, confusion, insecurity when the physical symptoms appear.    

Interestingly over the last few months, these symptoms have become a lot worse, continually changing in how they present themselves.  Along with that, there has been the growing frustration and annoyance  around what I can eat, drink, how much rest, etc and wanting to give it all up and just eat what I want.  Then again fear, confusion and insecurity appear.

Why does this area still look so real - the physical symptoms keep changing and reappearing as more severe?  Are the symptoms pointing me towards the resistance?  Where to go with this?
