Ugh this is a tough one

Lost my sister 4 months ago, started a new job in the ED 2 months ago as a PA. Been tough but has given me purpose in life again. Today I was let out early from my shift. As I’m driving, I happen to watch a motorcycle crash. I jump out of the car and see a disfigured body with a very deep laceration to the neck. They were already pulseless and pale although I was there within seconds. I performed CPR until EMS got there and they called TOD. I guess I’m here to vent. Never thought I would come across something like this outside of work. It’s hard to see. And it’s different when you’re the only one there with no team. Anyone been through something similar?
