Sorry to be so dramattic, but its a reality we all face from ana and mia. In reply to what you said, you donthave to be throwing up 20 times a day to be a bulimic, I think its the state of mind and the purge / binge cycle that classifies you as a bulimic.. But you dont want to get to the stage where you are diagnosed with bulimia. As you said, there is still hope, and if your on this website you have probably read hunderds of stories about how eating disorders are destroying peoples lives, bodys and minds.
You need to think about what causes you to eat the junk food and then want to throw it up. Is it because you dont want to focus on another problem? Is it about having control? I dont know anything except from what youve told me, so I cant help you much. That is good that you dont do it more than you do already, because theres probably a lot of damage atm being done to your esophagus, liver, heart and funtion of your body.
How long since you started this? Post me back, hope you are doing well.
