When you loose someone you love It changes you. You're never the same person you were before. You adapt. You adjust. But it still hurts. It hurts because that person mattered to you. Because you'd hoped that person wouldn't leave. It hurts, because deep down you hoped with everything you had, that that person would be the one person to stay.
You don't ever really recover from pain like that. You grow. You learn. But you don't forget. You never forget.
