Marianna, I don't know if I can help you or not, but

to you regardless!
I used to be an emotional eater, but I'm not really any more. Hormones, sometimes, but that's not really the same thing. What I did was just try to find other ways to cope with the emotions. I know that sounds pretty basic, but it's also really hard to find a whole new coping mechanism - the old one is so comfortable, and comfort is often what we need for coping. I try to stop myself before eating and decide if I REALLY am hungry or am I just depressed/angry/hurt/lonely/anxious/whatever? If I decide it's emotional, I try to consciously decide to do something besides eat: listen to music, call/im/email someone to talk to them, write a letter, go somewhere, or even (in true desperation) clean! Actually, cleaning while listening to some really upbeat music is an excellent way to cope with negative emotions while avoiding the munching blues (you can't eat a pint of Ben & Jerry's while scrubbing the toilet!). The music will help perk you up, and then, after you've cleaned, you have the satisfaction of a clean house (or part of it)! Another thing that really picks me up when I'm down is to go do something nice for someone - visit someone who can't get around too easily, write letters to those far-away relations you KNOW are dying to hear from you and missing you terribly, take something nice (flowers, food, or whatever) to an elderly neighbor, clean out your closet and take the clothes you don't wear or fit into anymore to a charity, or something along those lines. Doing things for others focuses our minds on other people instead of ourselves, taking us out of ourselves and our moodiness, and it makes us feel good to do things for others, especially those in need. And there's no shortage these days, sadly.
Good luck!
