I just recently had a baby

and well i'm experiencing the "baby blues"

.I hate feeling this way.I'm sad, afraid,i'm having so many different feelings.I think I was depressed during my pregnancy to.I have a while b4 I go back to the dr's 4 my 6 week check up.I am going to tell her how i've been feeling and hopefully I get on some meds,but I dont want to wait that long.I need to start feeling better now.My question is,do my dr have to refer me to another dr who deal with this type of medical condition and do an evaulation or can she just give me a prescription????
Thanks ~arica~
