Hey there, and
We have a great group called the "40-somethings", and you might want to hop in there. You might also want to check out our forum for those Dieting with Depression, as it can present unique challenges.
In addition, we have groups by eating plan (are you counting calories? Focusing on whole foods? We have forums for those and other plans) and a whole lot of smaller challenges, so look around.
Stick here and keep posting. Can't wait to get to know you better!
