First thing - you are not alone! So many people here have similar problems with binge eating when stressed. I sure do, though I've managed to decrease the frequency of events and they are now few and far between. You can control it, it just takes time and mindfulness! Make a big list of all the things you could do to help de-stress, then when you are feeling bingey, pick something from that list and make yourself do it. Then re-evaluate how you feel after.
Second thing - There is a forum here called 'Chicks in Control' which you might find helpful. Everyone there is battling some kind of food-related control issue, such as binge eating.
Third thing - Welcome to the Flex area, and feel free to use the menu thread in particular! Tracking everything, even if you aren't at a weight loss level of intake yet, can do wonders for your commitment level and help you see just what you need to do.
