all it takes to reach that point is two things:
1. not knowing why you exist.
2. the feeling that you won't care if you exist for the parts of this big mystery you do like any longer (usually in this life we find things we like, such as lovers, friends, potato salad, etc. and there is no way of knowing if we'll even have that where we're going, if we even go somewhere when we're dead).
this person was on the brink of just not caring and ending it all, yet didn't go about it in a way that would absolutely accomplish it. why? because a part of her, a part she may have not even known was in control wanted to live. acts like this, i speculate, are almost an S.O.S. call to the immeasurable unknown. we fear what we do not know. and we, no one knows, where we will go when our body dies.
again, this is just how i, ME, feels. i could be totally wrong here, though.
