The greatest coping mechanism for all stresses of life is the act itself of personal development and learning
The #1 world wide cause of sickness is stress, the #2 is worrying about getting stressed. Relax, God's in control there is nothing to worry about. Spend a few minutes every day and night just to relax, meditate and pray and it all the stress melts away.
Happiness comes from the absence of stress. Stress comes from worry. How can you worry if God's running the universe?
So "don't worry, be happy"
