my son is now 1 week and 1 day old and i believe i may have ppd...

through my pregnancy i thought that would never be me and i wouldn't have to worry about it.. but since he was born I've just been having unwanted thoughts its like there is someone in my head putting horrible things in my mind ! this is not me at all and every time i have it happen i want it to stop so badly. im scared to tell anyone or my ob because i feel like a horrible mom. but i need this to end.. has anyone had this.. im not depressed but i believe this is another form of ppd... please let me know or give advice i really dont want pills if i can manage it myself id like to..
