someone told me once: When you feel depressed and you think your life is the worst on earth, then see in the sky, it will give you a kind of peace, because when you look into the sky you will know that your problems are small and nothing special, because in this endless sky is so much more you don't know and you'll get maybe a little easier with this.
Since then I often look into the sky when I'm felling unhappy, and it works out. I feel more comfortable with my life and it makes my feelings easier...
