Is there a term for the opposite to suicidal?

It occured to m today that, while I don't actively want to die, I'm not exactly... whatever the opposite of suicidal is either. If death occured, my response would mostly be a tired "ehh" or maybe even a "at least I don't need to go into work on Monday".

I struggled to put this into words though. While not actively depressed, I appear to be lacking an attachment to being alive. I am non-non-suicidal.

Is there a word that describes this joy of, or desire to continue being, alive? Or a lack of it?
