HERE IS MY TAKE:
1- diet pills and now water pills.
2- How many calories a day? !!!
3- You throw up some times more than three times.
4- There isn't a day you are not worry about carbs and calories.
5- Recent loss weight, escalating the last few months...

the combinations of this things (not just one thing) leads me to believe that even I don't know what the label for your eating disorder is, it sure sounds like there is one.
