What do you suggest to be less anxious and happier?

Coordinate: Progressive relaxation and deep breathing can help with anxiety as well as things that can be calming for you such as long walks, cold showers, listening to music, meditation, yoga, exercising etc. Each persons calming technique is different. As far as being happier, no one can tell you how to do that. Decrease your stress levels and learn coping techniques. Utilize your support system.

Happiness: Dr. Refai shared several methods to cope with feelings of anxiety and unhappiness. Ultimately however, you need to explore the reasons for your unhappiness and distress. Occasionally the issues relate to your external situation, which you can change (with planning & effort). More often the reasons lie inside your own perceptions & attitude. Address these with a good therapist & free yourself.
