All the time sweetie! I have been dealing with depression and being overweight for as long as I can remember...and I'm only 30! It's a hard balance! I know sometimes I feel like I'm punishing myself when I can't have crappy food. Then I have to think "no Diana you are rewarding yourself - you are going to be skinny someday"!
I hope you start feeling better soon! I don't know if the sunshine is out where you are at - but I know that always makes me feel a little better - even if I'm just sitting in it!
