I knew exactly what to do in the case of an medical emergency that popped up and I didn't do it today. The person is okay but I can't stop feeling guilty over it.
Is it because you hate that person that you didn't help him?
No, it's just that he is a jerk. I expected him to listen to me, but he wouldn't listen.
It is hard to help people when they don't listen to us but you shouldn't feel guilty for not being able to do more. It is the person's responsibility to do the right thing.
I would have felt better helping him anyways. It's just the way I usually am.
Guilt will eat you alive. Just let it go and be free. Next time though help anyone no matter what you think of them, that is what a true professional medical professional does.
