Is this Postpartum Anxiety

I don't know if this is PPA because it's not extreme, but it never crossed my mind after Che was born. I get these ugly feelings that I might lose my children. Like they are going to die young. I can't even imagine the grief. I get anxious to leave them for fear of missing out on minutes with them. Maybe it's coming from the guilt I'm feeling about going back to work.

I mentioned the guilt to my parents. I worry that the kids will feel sad and question why I leave them. My mom asked if I remember being sad when she left us for work. I do not.
