Im overcoming bulimia all on my own, i seem to be out of the woods now, although I do not recommend not seeking medical help. I just felt for me it was the right decision, although I have spoke to my doctor about it twice, he just gave me a self referral form to get counselling. I just felt like I needed more than that or go it alone. But yes, go seek help as I think yours seem to be more severe than mine, and it isnt weak to ask for help its actually more courageous. One day I just really thought long and hard about why I developed bulimia in the first place and realised that i would never be able to be the person I wanted to be with bulimia and decided to change. Im like 6 months free from it and happy. You will get there if you want to help yourself. good luck
