What's the opposite of envious? For instance, I felt X when I got accepted into MIT and my sister did not. Or, when you feel bad for being lucky, when someone else is not.
By googling, I found unenvious but I'm afraid the word might not exist at all, because the Cambridge dictionary has no entry for it.
I feel bad in the first example because my sister and I wanted to study together at the same university. I'm quite happy that I got accepted, but sad at the same time because my sister did not.
