Dead or alive

I dunno what life has for me at the end. theres so many things i dont know. will we be together forever? , will our love last? .... i dont know but i do know that your smile lights up the sky i know that every time I'm around you i get lost in the moment. i know that i really do love you and my love for you grows everyday.
why is happiness running from me why does it feel like my hearts hanging from a tree and each breath is getting harder and harder and all my feelings are at my finger tips why is love killing me but keeping me alive
