Sandi,
Jacob is a fortunate boy to have such a caring mom! I know exactly where you are coming from. My daughter Katy is my motivation and weight loss inspiration.
To help me keep focused on why I am doing this - here is a picture of my goals page that I have up at home and at work were I see it everyday.

I wish you the very best. I know you can do it!
