ZombieOutbreak

Lately I've been working on my acne more and more, getting it a little more under control and its not as bad as it has been in the past but the one part that beats me.. is the mental aspect..
I've been using on Minocyclene, taking the proper vitamins, doing my own regimen and everything but.. my mind is the part I can't seem to conquer
Every single time I eat something, either junk food (which is very rare.. maybe once every couple months), pork, chicken, even something like toast with peanut butter or jam on it, I freak out inside thinking "great.. what if it makes me break out" .. and if I don't drink a certain amount of water each day I worry.. this all happened after I had my wisdom teeth taken out and had to switch my diet for awhile..
Please.. if anyone has any suggestions of what to do it would be much appreciated .. thanks!
