You say not what you feel, for what you feel may not be righted by others. The others are more important and the you must subside for the you to survive.
You want not what you desire, for it may not be desired by others. And you must desire like the others.
You crave not for this loneliness to go away, for it will not. You are apparently born with it and must live it until the loneliness abandons you for another. You must know then that that is the end.
