Hi garden gal! On the depression, I'm there too, and it really sucks. Hugs to you.
It can definitely be harder to post at such times! One thing I've found helpful is to join in on some of the lighter stuff. Diversion and participation. A two-fer.
There are a lot of games and such. Since your name is garden gal, perhaps you'd particularly enjoy http://forums.psychcentral.com/showthread.php?t=177880 "Our very own botanical garden". And there's always http://forums.psychcentral.com/showthread.php?t=152029 "Funny Stuff" which has funny pictures and jokes. Anything that can bring even a little grin is a good thing...

Hope you are feeling better soon!
