I have a new bit of advice up on Bitch Magazine for you to read.
In the meantime, here is my unsolicited advice of the day:
If you are feeling blue, give someone a gift (without expectations of a response), get outside with the dog, read a chapter of a book about something bigger than you, and watch your favorite t.v. show. It may not chase the blues away entirely, but at least you will be spending your time well instead of digging around in the dumps (or on the internet).
