Hi MOB, first thing, don't stress out or guilt yourself too much for the wedding: 20 pounds is perfectly doable by September, and probably even some more
Getting rid of all junk food in your house is a pretty good thing to do (especially if the nearest shop is a bit far, suddenly it's not so tempting anymore when it's not right under the hand!), but it doesn't stop the "frustration" feeling, or the stress, if this is what makes you feel like eating. Is there a way for you perhaps to do something completely different when you're tempted to eat? If you have the time or the opportunity to do so, perhaps you can go have a walk in a place where there aren't any stores nor temptations, run a bath, go to a gym, or anything that isn't compatible with the activity of eating? I've found out that it can work wonders, as by doing so my focus is less on the food and more on the activity. Maybe it can work for you as well?
In any case, I hope that things will soon improve for you, and that you can "get back on track"
