Make it the same time in the same place every day. Spend 30 minutes thinking about your concerns and what you can do about them. Focus more on what's really happening. You can learn ways to help you relax. These may include muscle relaxation, yoga, biofeedback and deep breathing.
Muscle relaxation is easy.
Start by choosing a muscle and holding it tight for a few seconds. Then relax the muscle. Do this with all of your muscles. Try starting with your feet and working your way up your body. Confront the things that have made you anxious in the past.
