Bulimia Help

I am so mad at myself, I was doing great for weeks and then i slipped up an b/p once, and again the next day, and now six times today! Im so stressed I work seven days a week and go to school, Im so tired! But I have to pay bills so I have no choice.....It started today when my boss called and asked me if I could work more, i felt like I couldnt say no...and I spent all day ( the only time all week I had off) B/p and that really sux, cuz I could have chosen to use my time to see my brothers and sisters, or go to the beach or something. Its like why am I working so much if i just waste money on food? I felt so insatiable, then sick, then insataible again, I feel like a monster. I think the insatiable feeling is worse then the pukeing sick feeling. I HATE THROWING UP!!!! IT HURTS!!!! Every part of this sick cycle feels awful! Why do I do it? I even did it at work, I think being tired and stressed are triggers for me, I have to let this go......Thanx for letting me rant
