Who to call

Mrs.JK

I only have an OB, no general dr. I know I had pp depression after I had my DD. But for whatever reason was in denial or embarrassed to admit to it. Now I feel so hopeless, tired, and very moody. It could be partially due to adjusting to changing shifts at work (went from 2nd to 3rd). My question is do I call my Ob? Or find a GP dr and get an appt ( which could take months to get it)
