S.M.
C., I'm so sorry you feel so alone. You shouldn't. It is VERY common to suffer from PPD. How horrible that your doctor made you feel like that. I suffered from PPD after the birth of my twins, it was the nurse practitioner at the OB office that actually gave me some medication and recommended some doctors.
I do not actually know any doctors in Westchester (though I did grow up in Briarcliff, I now live in Hoboken,NJ) but hopefully some other moms will chime in on specific recommendations.
Hang in there, and you are doing the right thing looking for help.
Warm Regards,
S.
