Need support this time around

I am in need of motivation and support this time around with my weight loss. In 2004 I got down to 140, then a year later got back up to 170. Last summer I weighed 140, and now yet again I am up to 172. I have been struggling with over eating, yo yo dieting. I am so disgusted with what I see in the mirror! I need to do this if not for me then my 4 children.
