Wow, this is exactly what I went through, anorexia the bulimia then saw a councillor then a hypnotherapist. To be honest the only thing that has helped me is going on antidepressants, sertraline, which is proven to help many people. I have now had 3 months of CBT (nhs funded) which has been amazing. I have stopped being sick altogether (3x in past six months) and although I do still have phases of binging, I'm in one now I am so much better than I was and the main thing is that I'm not ruining my body with the binge/vomit cycle. Cbt will help you to identify coping mechanisms. Also, roughly how many calories do you eat per day (on a normal non purge day)?x
(I should probably add that I didn't take the antidepressant route lightly and over the past year have managed to half my dose but am not quite ready to come off them completely).
