Welcome to 3fc bears, you'll fidn fantastic support here!
Firstly..I'm an emotional eater too and it is fairly common. This is something you'll be interested in, if you pick up an apple 42 times instead of (insert whatever bad food you crave here) when you're feeling down, then you have kicked the 'addiction' if you like. So when you're feeling low...maybe just try picking up an apple instead? When you crave the food, what is it you're looking for in that food - happiness? Will you find happiness in that bad food? And do you feel guilty afterwards?
Really you just need to confront the comfort eating, because it's a habit and habits cant be kicked untill you understand them.
Best of luck, and its really great that your family support you in this too! Keep us informed
