Whether you are living with anxiety or you are an O.C.D. personality type, you may find it helpful to stop “looking back”. When a bout of worry or anxiety arrives, try to focus on it and develop ways of coping with it; for example, it may be helpful to re-direct your thinking. Focus on something quite different; even making a cup of tea or going for a walk in the garden may be useful. In other words do not waste mental energy on trying to work out why you are anxious.

Even when physical ailments occur, try not to think of reasons for the head ache, upset stomach, back pain, etc. Just concentrate on dealing with the symptom as best you can and try to avoid worrying about the cause. It only makes the situation more stressful.
Good luck!
