It's an incredibly hard habit to break. It's just like any addiction though. There is a reason behind your overeating, which you have discovered to be stress or emotions. Just like what everyone said what I want you to do is plan. Planning is going to be key.
First off, get out of the house any foods that you could abuse by overeating (ie chocolate, fried foods, carbs, etc). I mean you can't eat if it's not there, right?
Next you want to pack your snacks for when you're going out. Make sure you're carrying some nuts, some fruit or something that is portable but healthy when you know you may run into something that'll trigger you.
Plan your meals. And if you plan your meals the with the right combination of protein, carbs, and fat you're likely to be satiated for several hours.
Then when you feel the urge to eat, stop yourself and ask "Am I truly hungry? When did I last eat?" And if it's been more than 3 hours then you're probably are hungry but if it's like half an hour after you've eaten something, you're more than likely fishing for something to calm an emotion.
Next what you need to do is see what is the driving emotion behind the sudden urge to eat your face off. You have to really bring awareness to your actions rather than phoning it in and just reaching for that candy bar. You have to say "Ok so if I'm not really hungry, what is causing me to want that candy bar? Am I anxious? Am I stressed? Angry? etc." Do your best to try and identify the emotion and see what it's based off whether you have a deadline at work that you're anxious about or you're worried you're not going to be able to do all the errands on Saturday that you think you need to do. Once you've established the emotion that you're feeling and what's specifically triggering it you can start to recognize what you can do to make the situation better for example with the deadline, sit down plot out the work and what needs to be done when so you have a little timeline to follow to make sure you get the work done before the deadline. This way you're being productive and know what you need to do to get the deadline completed and also you can allay your fears concerning it so you won't eat.
It's a really hard process. It's taken me several months to get it down, but once you do it's something that is so second nature. Right now I'm working on trying to do it with emotional eating related to things that I cannot identify or things that are out of my control that I can't do anything about to really make the situation better. That seems to be the hardest thing for me thus far. Because I know once I settle down and see what can be done for the things that I can change or do something about I relax almost immediately and no longer want to stress eat, but with the things I can't do anything about or I can't identify I still find myself eating away and not understanding why it's going the way it is. This has been happening for the last month but I'm really starting to open up a little more and bring my awareness to myself to try and identify those things better so I can do more to deal with it.
Good luck, sweetheart! I'm sure you'll be fine and you're baby's surgery will go beautifully!
