I've been there before, and have been there recently. I'm sorry you are feeling down. You CAN do this. Sometimes it helps to just make small steps. You've started walking, thats great! Maybe the next step can be just recording exactly everything you eat, just writing it down, not even counting the calories. When I start to slack off, I start doing that. And when I see all that I'm actually eating, its easier to start cutting back.
I'm trying to get my motivation back. I only started working out again about 2 weeks ago. That was after everyone at work told me I looked sick, and I was so so tired. I started working out that weekend, and have felt so much better since.

Please feel free to PM me anytime.
