How can one be extremely happy and very sad all at the same time?

My life is finally turning around… and I’m over the moon right now.

But then last night, I got a call from @scamp, who some of you know is a co-worker and close friend of mine. Her grandson, about 2 weeks shy of his second birthday, drowned yesterday. He’s in a coma, completely brain dead, and they’re taking him off life support today sometime.

I keep going back and forth between being so happy for myself, and yet so profoundly sad for my friend and her family.

Have you ever been in a situation like this? When your emotions were on both ends of the spectrum from one minute to the next? How do you not feel guilty for being happy during a tragedy?
