Just follow your mood today, and wherever it leads you will be the right place for you to be. If you're feeling depressed, you're feeling depressed for a reason -- so don't try to cheer yourself up. And if you're ecstatically happy, you're ecstatically happy for a reason. Do not try to make yourself feel a certain way -- especially for the sake of making other people comfortable. They can deal with you however you are, as long as you are your usual polite self.
