I know how you feel, self-sabotage is 90% of the time unintentional. You just really need to focus, the reason we eat when we are bored/stressed is because its something to do, it makes us feel better TEMPORARILY, and we eat what tastes good!
The main thing I find to be easiest, is to look at it as a habit. You have nothing to do...so your body instinctively migrates to the fridge or pantry in search of "taste but entertainment", you grab what you like, and you scarf it down. The trick is to REALIZE when you are migrating, and stop dead in your tracks, and seriously think about if you are hungry or not. Its ok to "nosh" on something (just make sure it has some nutritional value), and have a glass of water with it, wait about 10 minutes to see if you are still hungry. That SHOULD curb your hunger for maybe an hour or 2.
Another way is to keep your mind occupied with other things! Take on a hobby you always wanted to try, start blogging your weight loss, go for a walk, go for a bike ride, anything to keep your mind occupied.
I would do some research on small snacks that are good for you, and curb your appetite until your next meal. See what will work for you, because what works for 1 person may not work for the next. Personally I stock up on light n' fit yogurts, those 90 cal chewy bars, and pita bread with humus as snacks to have throughout the day, because those work for me, and they all have nutritional value. So do a little research and find out what works for ya! Good luck!
Hope this helps!
