Failing at this

I started out so well.  I was doing great, and then the stress level at work went up 10 fold which means stress eating for me.  What doesn't make any sense is I know this about me, however, I still end up saying, "Oh forget it. I'll eat ***."  It is not a good way to go. I'm up almost 2 pounds and really need to get myself under control.  Not only am I not losing weight, but I'm gaining back the few that I did lose.  So, I need a plan of attack for this week and I don't know where to start.  I guess I will try no more snacking between meals, other than maybe low fat yogurt or fruit.  Something healthy, anyway.  So, hopefully I can get back into this and stop hating myself for failing.
