I relate to this.

if it's someone I know who dies, I tend not to show any emotion (I almost am sat their thinking, this person is in a coma, they'll be fine soon), and the fact that they have died and I will no longer see them doesn't phase me (that, or I just can't grasp it)

but when it comes to celebrities, I'm a blubbering mess

I remember when michael jackson died, I felt like I'd lost a brother and cried for an entire year (I wouldn't play his music, hear his name, anything) and the same for robbin williams, carey fisher, and anyone else you can think of.

I even worry about some of my favorite celebrities dying

but no one I know in person. it is really strange
