Dear Louise: I had my bulimia under control. But the demon has returned

I am writing to you in utter despair. As a lifelong bulimia sufferer, I thought I had the illness controlled relatively well but in the last number of years, my demon has returned.

I lead a very busy life — I’m a mature student in college — and I separated from my partner but the separation was my decision. I hate myself when it beckons as it ultimately makes me fatter, it has the reverse effect on me. Help! I’m in a mess.
