Hi, and Welcome
CONGRATS on the 7 lb loss
I do understand what your going through. I gained a ton of weight after my sisters death in 1997 and I still can not seem to get it under control. I think for me, its more habbit and mental.
Since the passing of your father is so recent, I would suggest seeking some sort of grieving counceling. Some churches have them (free), you just have to look around.
Struggling with depression and grieving a loss can really take its toll (I'm proof). So stick with weight watchers and get some counceling, I really do think this will help you sort out all kinds of feelings.
Hugs and Kisses
