When you find yourself caught up in an emotional or mental "firestorm" not to your liking, there is a beneficial way of counteracting it. BREATHE. Lock in on your breathing. Concentrate on the rhythm and depth of your breath. Really focus! Try and slow it down. In through your nose and out through your mouth. Slower--deeper. To the exclusion of all other stimulus. Slower still--deeper yet. Feel the expansion of your lungs when you inhale, the compression when you exhale. If you are in a position to do so, allow your eyelids to close for a short time. When your mind grasps at the thought that upset you, ignore it and refocus on your breath. Stay with the rhythm; ride it in, ride it out. Peace in...distress out.
As you re-engage the situation that upset you, realize you have choices. There is a wide range of ways to react. If the provocation has been overt or even deliberate, it stills does not limit the number of options you have in which to respond. If the adjectives versatile and flexible are appealing to you, perhaps now is the time to demonstrate them. (see the post "Anchors Aweigh" 1-5-13) Whatever you decide to do (as long as you are ready to accept the consequences of your actions) is exactly the right course of action. The gift is in the experience and you are ready for it.
