Why can't i do this?

Why can't I end this?
and just let go
so close to the edge
overlooking the cliffs below

Why can't I forget the past?
and let memories fade away
crying my heart out
I simply drop the blade

Why can't I do this?
water rushing over my face
I start to cry, thinking of you
I just wish I could leave this place

I know why I can't do it..
I feel like your still holding on
I know you wouldn't want me to do this
but without you I just can't go on
