Hi GL,
You do NOT suck dear!
I think one of the best things I have learned from this board is that this WOL has to be taken one day at a time.
Step back and take a breath. Has anything changed recently? Added stress or happiness? Can you get some of the high carb food out of the house? I believe that everyone stumbles, and if this WOE is for you, you WILL get back on track. Keep your journal up and your spirits. You WILL be OK
