“Your fears are not facts”
This is one of the most important things I learnt in therapy. By acknowledging that the fear you feel is not a true fact of how the situation will be is beneficial in reducing feelings of anxiety and despair.
The below link gives 10 ways to help overcome fear and anxiety; you will probably find one or two that really help you as an individual. For me distraction is the holy grail of reducing anxiety, but the logical scientist in me likes challenging fears through rational thought.
Distraction – engage yourself in an activity that requires mental focus, e.g. playing a musical instrument. It’s difficult to maintain negative thought patterns if your mind is busy elsewhere.
Rational thought – Is your fear likely to happen? Has it happened before? What can you do to change things? What is the worst that could happen? What is the most likely outcome? By interrogating your fear it loses its power over you and you can take control.
