I think Blastoff gave excellent advice!!! My friend was diagnosed with PPD and she didn't get help. She ended up spending weeks in the hospital until she was stable enough to leave. It's very common for this to happen to women after a baby, mostly because of hormones being out of wack. Let her know that it usually doesn't get better on it's own, so she needs to see someone...the sooner the better!! I believe there is also a PPD board here, so try talking to them as well. I'm sure they can offer great support!!
