..
i know how you feel. it's like you kind of just don't care ... not in a mean, "you could die, whatever, it doesn't matter to me" kind of way, just a "i'm living my own life, and you're living your's" kind of way.
i actually think this is a pretty healthy way to be. part of our sickness in the first place is that we get overly-involved in other people's lives, you know? controlling and whatnot.
maybe this isn't what you're talking about ... but maybe it is.
best of luck either way.
