Count your blessings. Once you realize how valuable you are and how much you have going for you, the smiles will return, the sun will break out, the music will play, and you will finally be able to move forward the life that God intended for you with grace, strength, courage, and confidence.
Peace is not something you can force on anything or anyone... . much less upon one's own mind. It's like trying to quiet the ocean by pressing upon the waves. Sanity lies in somehow opening to the chaos, allowing anxiety, moving deeply into the tumult, diving into the waves, where underneath, within, peace simply is.
