*******Update:
Well, I walked in, started shaking and crying, told her that I think I have PND and then cried some more, then she asked me a few questions and asked me if I wanted some tablets. I said no, and that I know they have an effect on breast fed babeis so I can't anyway. She asked me if I want to speak to anyone and I said yeah, and that talking about it helps. That was pretty much that. She printed off some information, refered me, and told me to come back in a week (or I could go back sooner if I needed.) That doesn't sound like she was much help but she was. She was so understanding and knew exactly what I was going to say before I said it. I feel so much better just for that little chat. Onwards and upwards!!
