It is okay if the world doesn't know, if it judges you by what it knows, holds you captive in the confines of what they believe you in your position should be grateful for –just let them be. What do they know about you and the things you treasure in your heart, the hurts you bury, the wishes you desire... the world doesn't know.
Let the world trample this image of you that they see. It is not you it demeans.
You are not the world's expectations of you, you do not need the approval of people who think you should be happy when you are not, you do not need to explain the flaws of your character... justify them so that you're able to make yourself worthy of being weak...
You are human and just as you are, you are capable of strength. Your dignity is always yours. Let them be.
