I was thin in high school and then got married and ballooned from there. I divorced and am remarried. My kids rarely see their dad. This is sad, but they often tell me, "Mom, please don't die because we don't want to go live with him." If that wasn't motivation, I don't know what is. I can't deal with the guilt of knowing that all I had to do was quit stuffing my face and making bad food choices and that is what may keep them from living with their dad one day. I can't predict the future and know when I may die but if I have a choice in the matter, it won't be because I didn't try to change things. I'm doing it for me and sometimes when I want to quit, I do it for my kids until I get back to wanting it for myself. Does that make sense?
I'm not saying it's easy for me at all...because I have always "lived to eat" but now I'm trying to learn to "eat to live". Best of luck to you and I hope my thoughts may have helped you in some way.
