So happy you are doing so well!!! I agree with Cate, just getting out and getting moving is so good for the soul no matter the speed! I think I was a little depressed as well, and it's taken a while for me to figure out how to take care of myself, too. It's so great to hear you are in a much better place in that regard. Are you seeing someone about the achilles tendinitis? Is that something where you just have to take it easy so you don't exacerbate it?
Big huge congratulations on the 20 pound loss! Sounds like you are doing amazing all around!
