I do the same thing - run to food whenever I feel anxious, mad, sad, etc. Only recently did I realize I've done this since I was 12 - when my parents got divorced. Over the years, I've managed to eat really well and not use food to anesthetize myself -- until the last couple of years. For some reason, it's like decided to just give up taking care of myself.
Anyway, I'm tired of it. I want the old me back. I don't know what coping strategies I have/use. I'm just fed up and ticked off at myself for becoming such an emotional eater, so I'm saying "NO MORE." Obviously working out and making good food choices help immensely.
I've been telling myself (almost daily) that NO ONE is worth getting upset over and over eating. In other words, taking it out on myself. Most of us have the freedom to make good food choices, even if we are dirt poor.
Are you familiar with Geneen Roth? Check her out on amazon.com. She's got some great books on emotional eating.
You can do this. It's tough, but you can break away from the emotional eating.
