Welcome back, I'm glad to see you again.
Hey girl, don't be so hard on yourself. Old habits are very hard to break and unlike smoking, drinking, or gambling, it's not like you can just quit eating.
Take a moment to figure out what undid your progress (I am guessing you have already done that) and come up with a plan to undo your undoing. One day at a time and 1 foot in front of the other. You can do it!
