Take 2 minutes today to allow yourself to hurt.
Let the thing(s) that are eating you come to the top of your consciousnesses, one at a time.
Then follow this flow chart:
-can I take any action right now
-No? -put in a calendar reminder to take a step tomorrow towards either changing the situation, or changing the way you react to it.
Repeat for each of your 'things'
Breathe in, breathe out, repeat.
