Im 14 and im drinking this diet drink but it makes me feel really sick i also puked up some pink stuff.?

5'6 and 130 lbs....and 14 years old....there is no reason you need to be using a diet drink.....in addition to the fact that it's probably unhealthy if making you vomit.....plus, if you're bulemic, you've got a serious health issue that you need to take care of. PLEASE go see a doctor, and also a therapist; believe me, it will make you much happier in the long run!
