Why am I here?

I have been having problems with depression, which I recently found out is Postpartum Depression. I didn't just have a baby, I have an 18 month old and have been extremely happy since her birth. But, I had a miscarriage a few months ago and have been depressed ever since. Anyway, I feel like crap. I feel completely worthless. I have moments when I'm as happy as can be, and then others when I want to lay in bed all day and not move. I have nothing to be sad about, really. I'm happy with my life. It's just hormonal imbalances, I guess. I'm just having major mood swings and my hormonal craziness is causing depression. It sucks. Hopefully they can do something to help me, I'll be calling my doctor today to set up an appointment. Thanks for reading.
