There's a famous Latin motto, Solvitur ambulando, which means "Solve it by walking." When faced with difficult feelings take a walk for at least 20 minutes - ideally in a natural setting such as a park or wood or among the hills or at the beach. Adjust your mind to the rhythm of your footsteps. Allow any erroneous thoughts to be jostled out of the basket you are carrying inside your head and fall by the wayside. By the end of your walk you will see things in a truer perspective.
