Whenever you feel a negative emotion be alone in a room and just sit down with it and feel. Don't judge it, criticize it, intellectualize it, explain it away. Allow yourself to feel the pain. It's okay. Accompany it - breathe into it - and after a while, you'll feel the anger or fear or sadness lose it's urgency and power. Allow God to tenderly embrace you in your pain. And then, at the right time, you can let go.
