This pain is in vain

Is all my efforts in vain? Is all of this just to cause pain? How much can i endure? How can you not be sure. Do you want me just let it end. We used to be the best of the best. But now i seem to be the one who's just always there, always here to care. Will you one day show me its all worth it? Will you tell me why it hurts so much. Will you be my love and life and such? We spin in and out of joy, up and down this life's ploy. Im holding on with everything I've got, but i think you left this ride before the start.
