My first experience with depression was postpartum, too. I would encourage any mom who believes she may be suffering from this to get help, and if you don't get a satisfactory answer right away, keep trying!

I made the mistake of calling my OB/GYN's office and asking for a referral and got a totally unsatisfactory response. I ended up getting help from my actual OB/GYN eventually, but I stupidly did not press on after receiving that first unhelpful reply.
