The Life of Many

Hey... I have a question... Do you know the feeling of being alone? The feeling of emptiness, stress, and despair? The times where you feel as if people look at you with a lot of emotion, not for you. But for them? As if they use you for their own good, and then, when they don't need you anymore they just.. They just simply throw you away, because you have no more purpose. If you do then... I don't feel sorry for you. Because if you know that feeling, it just suddenly becomes your life. And you can never back away from it. So what's the point of saying sorry, when your life will never change?
