Why does it kill me? Why?

I keep thinking about this one girl and she seems to be like everything I think about now these days. Nothing to do but just think about her. She kills me every time I think about her. But when I hear her voice and see her smiling face, it's like all my worries are gone. I always wonder when that day would come when I know for sure I can get a date with her. I know it will never happen but for some reason, I just keep pushing myself to impress her. She's unforgettable. I just wish I can forget about her sooner or later. It's like poison slowly killing me. Well just gotta get through this year and hope summer clogs my mind with the joyful memories.
