Take this moment now to do the following:
1. Take three loud breaths in through your nose
2. Exhale long and calmly through your mouth
3. Whilst doing so, focus on allowing all the feelings of fear, resentment and anger to go with each exhale
4. Repeat stages 1 and 2
5. Whilst doing so this time, focus only on your breathing
4. Repeat every time you find yourself thinking of the past.
