While my degree is seeking to be an MD and not a psychologist, I can tell you that the only difference between Postpartum depression and depression is the involvement of a child in some way. He may have said you exude symptoms of Postpartum depression, but officially diagnosed you with depression. While my degree is seeking an MD, I am definitely no stranger to mental health and have been involved in it heavily over the past few years. The symptoms are virtually the same. Just to give you a little idea, new fathers can also develop PPD just as mothers. I would find it very hard to swallow someone diagnosed you with PPD being a licensed psychologist in all honesty. Again, maybe he said you display signs, but again find it hard to believe you could be diagnosed with PPD telling him you've never been pregnant at all. If he's that retarded, I'd seek another psychiatrist in all honesty and not take a single pill he gives you.
