Post Partum Depression

After suffering through anxiety for the duration of my pregnancy, I am now dealing with what I think is PPD. I feel numb. I cry a lot. I miss being pregnant. I love my daughter, but I have horrible thoughts, like giving her away. I'm scared. The thing is, I don't know who to tell. It's hard to get ahold of my OBGYN, but should I inform him? Or should I speak to a psychiatrist right away? My town has limited medical staff so it will take about a month to see the psychiatrist. I just want help. I don't want to spend any more time feeling horrible, and like I am decaying and wasting away. I want to be happy for my daughter.
