I can answer questions about symptoms, what you should do if you think you have Postpartum depression, and I can give you, references to websites to help you better understand it. I cannot diagnose you, I am not a doctor.
I am a survivor of Postpartum depression, I was diagnosed with Postpartum depression, when my son was only two weeks old. I was told that the Postpartum depression I had was one of the worst cases. I was on Antidepressants, that saved me.
