When I lost my mother, I knew in the weeks following that I was depressed but it went on for so long after that, I didn't realize my depression was still connected to losing her, so I understand. I am so glad you have taken steps to get "you" back!
I love that you are going to quit smoking and congrats on the weight you've lost so far! Good job! By the way, we have a WW forum here, so be sure to check it out! Good luck! You can do this!
