Sad? Earphones in. Volume up. Ignore the world for a while.
Every man has his secret sorrows which the world knows not; and often times we call a man cold when he is only sad. – Henry Wadsworth Longfellow
Whenever you feel sad just remember that there are billions of cells in your body and all they care about is you.
But listen to me. For one moment quit being sad. Hear blessings dropping their blossoms around you. – Rumi
Ignore those that make you fearful and sad. – Rumi
