The other day I drove past a woman who was crying, and I can't stop feeling horrible about it.
I'm sorry you feel that way. Why do you think you can't stop feeling horrible about it?
I should have stopped to help her. Hope she's ok.
Just because you saw someone else being sad doesn't mean you need to let it affect you for a long time. While it's good that you have empathy and feel sad for them, you shouldn't be lingering on something that happened days ago.
But it's never good to ignore a woman who is crying. I shouldn't have just left her there in the middle of the night.
I understand how you feel, but it's not possible to help everyone you see that's crying. You shouldn't take on the responsibility of trying to make everyone feel better, because it's not realistic.
