WHY halloween!

I've come to the realization the halloween was my breaking point this year!! I've been so good eliminating bad foods and losing weight. Then here comes halloween, and of course my husband leaves the next day.
I'm stuck in a rut. I think chocolate has replaced my love and I can't seem to break the cycle. I was good and gave most of the candy away. But silly me kept alittle and my son has tons!! On top of that I can't seem to get the motivation to excercise. I'm sure with holidays around the corner we could call this a slight depression but this is ridiculous. I wish I knew what happened to the old me. I was just sooo good at it for over a year. My biggest fear is that while Aaron's gone I'm gonna go down the tubes. Eat away my being lonely. I don't even like to talk to my neighbors and that's just not normal. I'm hoping by writing this all down it might help me get a grip (as a snack on choc. chips!!).
I can't find the energy that I had before.....always tired and such. I hope I can break this bad bad habit soon before my ticker jumps from 5, to 10, to 20lbs up the scale.
