Fatigue. Take some time off fro your work. Make a day schedule and stick to it. Early in the morning in your bed, meditate on Universal God for 5 minutes (longer is better) irrespective of your religion. Thank Him for everything such as life, food, space to live, family, nature, water, air etc. Drink a glass of water.Go for a walk. Eat good breakfast. Talk to someone whom you trust. Watch T.V. whatever you.
