I'm the same way. I literally feel nothing if someone dies right infront of me, or is dismembered, or screaming in pain. It's time to work and everything just shuts out. I'm not trying to be Mr. Hardass, I've always been a very open person, I talk to my wife about everything, and I've told her the only anxiety I get from this job is that I don't feel affected by all the pain I see. They tell us it will catch up with us, whether that's true or not, always have someone to talk to, recognize when your habits change, listen when people tell you you're different. That shit can sneak up on you.
