The Cleveland Clinic offers these suggestions:

• Stick to a healthy diet, get plenty of exercise, avoid smoking and limit the amount of alcohol you drink.
  
  
• Don't allow others to make demands or set expectations for you. Say no, and don't be afraid to stand up for yourself.
  
  
• Take time every day just to relax.
  
  
• Set realistic goals and expectations for yourself, but understand that you can't control everything.
  
  
• Figure out what causes you stress in your life. Eliminate what you can, and learn how to manage other sources of stress.
  
  
• Remind yourself of what you do well and successes that you've had.
