I too am looking for support. I am 10 years older, 4" shorter but about the same weight and the same weight loss. It's kind of funny that the motto that you posted is very similar to the motto I have hanging in my classroom. My goal is not to perfectly preserve this nearly 1/2 century old body but to simply be healthy and give myself every opportunity to do the things that I currently do not have the energy and stamina to do. I am brand new to this site and am still learning how to post and navigate.
Oh, and I too have 3 kids, all grown and living on their own. I have three wonderful grandsons and two granchildren on the way. I am an energetic granny and the kids have lots of fun with me and I want it to stay that way. Good luck and Godspeed!
