I CAN'T LIVE WAITING FOR

Yes, I can't.
My life seems so small and I feel so sad, badly and thirsty of love.
Every time of my life I want try to be perfect for you but I can't live waiting for.
I can't change, I try to be perfect, but i can't be perfect.
Because I been like that all my life, you can't understand me, and I can't understand you, but I try it, and I waited that all change and I tried to been perfect. But now I know that the moon and the sun are the life but can't live together. And I can't live waiting for changes.
I feel so sad...
