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.
I believe that angels are forms, images, and expressions through which the essences and energy forces of God can be transmitted and that, since there are an infinite number of these forms, the greatest service anyone can pay the angelic host is never consciously to limit the ways angels might appear to us.
