Being an EMT has its rewards I’m sure. But a lot of it is showing up to help yet another person who hasn’t done anything to live a healthy life, or leads a violent life, or has abused alcohol or drugs or food, now demands the most expensive form of healthcare delivery we have, and is unable to pay a penny for it, and consumes resources that an accident victim may now have to wait for, and will go right back to those behaviors again and again.
Burn out is a thing in that line of work too.
