Wondering about the difference between having a reason not to live and not having a reason to live. Don't worry, it doesn't make much sense to me either. Other than there seems to be a definite distinction.
Also - on a related note - I think it's very sad, or pathetic, rather, if the only reason to live is for the benefit of someone else.
That said, and within the boundaries of AvPD, is it possible to reorient yourself and discover a reason to live? Existing isn't living, and it seems kind of pointless to me. I think I could tolerate life much more easily if there was a reason to do it. No clue how to go about it though.
