I was in disbelief the first couple months ….. someone was actually listening to understand not just to respond.. I was treated as a whole person not just my diagnosis. and the responses were the most educated on the subject I had ever heard ! For years I just got referral after referral it felt like nobody was qualified enough to help me I was close to giving up constantly getting sucked into whatever trend or injection people were using to fast / torture themselves thin .. believing all the advertisements claims constantly restricting and obsessing/dieting /suffering !!!!! Finding case-specific has changed my life and improved my health in ways I previously….. “and sometimes currently “ thought to be impossible … after 30 years of suffocating in false information I can finally breathe Because the truth is … A PERFECT YOU IS NOT POSSIBLE! A HEALTHIER YOU IS !
