When we're feeling a bit anxious or depressed, we tend to let worries circulate in our head and stopping what cognitive psychologists call "automatic thoughts" can prove difficult. It's possible to clear the cycle in a number of ways. Outside the exercises which you might undertake in the therapy room, concentrating on taking in the sights and sounds around us can help. Try to be fully aware of what's going on around you. If you are taking a walk, avoid looking down. Keep your eyes focused mid-range on your immediate environment and try to appreciate what is going on. This image is just a street photograph - people, colour and shapes. Instead of street works being a nuisance, they become a source of stimulation. Have a look at what's in the photograph. There's lots going on that we miss when we let worries dominate!
