A souple weeks ago at work, a co worker started having a stroke. My manager panicked and yelled " call a manager" and I ignored her and called 911.

I have been told that if the paramedics were a minute longer he would have been brain dead or dead.

Coworkers are tellign me that I am a hero and that I did the right thing. But I don't want people to tell me that. I mean I feel like I just acted like a human being. And it is really bothering me that people keep saying this. Also I can't stop thinking about the event. I think about it ALL the time, where as everyone else seems to have moved on. I just don't understand how people can go on like nothing happened.

I am constantely thinking about the event, what could have happened, how my co workers handled it.

What is wrong with me?

There's nothing wrong with you. I would tell people at work to stop it, it's bothering you.
I would visit the person whose life you and the paramedics and the hospital saved.
That's the only person who counts.
There are a bunch of old sayings which I can't remember at the moment, but they all boil down to being forever tied to someone you save. Some say indebted even. Why would you be indebted? Why not the other way around? It's a mystery you need to explore. Maybe saving someone adds a dimension of meaning to your life you didn't have before. So the homeless person given a meal does a favor for the person doing the favor. The abandoned dog makes the person who rescues him feel better. The life saved 'saves' the person saving that life.

But isn't that why we are here on this earth, to make life better for each other, even saving each other's life if it comes to that? I saved the life of my neighbor's elderly mother during the 1980s, and my life was saved in 2009. Karma, what goes around comes around. I will pray someone will be nearby, motherofgrace, to save your life someday.
