PPD blues

PPD is kicking my butt. It seems like I was hit immediately after giving birth three weeks ago. My doctor prescribed me with medication and said it would be awhile before it’ll work. I feel sad and miserable all the time and soooo ready to go back to work, but I’m afraid to leave my baby. I have no family and no one to talk to so I thought I’d let it out here. Lord, please help me.
