One song about a person

I don't know what's this feeling im feeling right now. It's rather weird. I'm feeling lonely yet not lonely at the same moment. I suppose i'm just afraid to lose the people around me and i don't know what to do. However, a line from the movie i watched yesterday made me feel better. I think its something like that lah.

"If the people around you didn't die, you wouldn't know how to miss them."

If only things were different.
