Flashbacks?

So I've heard that preemie moms sometimes suffer from PTSD. At first, I completely discounted that idea. Sure, it's traumatic...but that traumatic? Now I'm wondering about that. As I clean up and put away documents in their proper places from my time in Arizona, I can't seem to help but flashback to where I was on that day. At that moment. And I find myself feeling that fear and anxiety and sadness again. And sometimes it's overwhelming. This, too, shall pass. Right?
