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.
Realize that true happiness lies within you. Waste no time and effort searching for peace and contentment and joy in the world outside. Remember that there is no happiness in having or in getting, but only in giving. Reach out. Share. Smile. Hug. Happiness is a perfume you cannot pour on others without getting a few drops on yourself.
