Hi Kaybear,
Boy do I know how you feel. I lost 150 lbs and after the death of my sister, I gained back 80

This happened 6 years ago and I'm still having problems staying focused.
The only thing I can suggest is keep talking, get your feeling out, write it down if you have to. Find a plan and keep trying, don't ever give up.
I would also suggest finding a board, WW or right here, the depression board and post on the daily threads. Make friends and I honestly believe it will help.
I think for me is even though I am married and have a big family, I feel lonely ever since my sister left. I feel very negelected and I don't know how to deal with it. I also feel there is alot of other things as well.
Anyway I'm so glad your here and please come post on the daily threads.
HUGS, Leenie
