Worried about postpartum

Nichole
So a week before I delivered my mom passed away. I went back to work and went I to labor while at work thankfully I work I the hospital I delivered at. The next morning when they did the normal blood tests they saw her billyrubben (not sure how to spell it) was really high so they sent her to the NICU. We spent 4 days there under the light and finding out she may have her dad's blood disorder we got to go home. Now that we are home and settled in have been overwhelmed by emotions not so much about caring for my baby or even getting frustrated with her it's like I started my mourning process with my mom all over again. She was supposed to watch her when I went to work and she was supposed to be there for delivery. She was honestly my best friend the one in went to for advice and now I need that advice more than anything. I was wondering if I should speak to my doctor about postpartum or is this just me mourning the loss of my mom. I'm not always sad or upset but I'm just worried about getting good to that point and when to get help.
