Aaah, emotional eating (been there, done that).
Here's a short story. My (ex)boyfriend lives out of town and I went to visit him for four days. When I got back I found I had lost four pounds. The day after I got back we broke up. I was devistated. I became a complete wreck. Four days later I had gained back the found pounds I lost.
Depression (even temporary) always leads to eating for me. I try to not do it but I do like others have said.. "If I can't eat ice cream for dinner after having been dumped, then when do I get to do it?"
I don't know I'll ever stop doing that. The important thing is to dust yourself off after a few days and get back on track.
I think icecream was invented for the broken hearted.
