3 Steps

1)  Notice it:  notice what's happening;  your thoughts, feelings, behaviors, the behaviors of others, etc


2)  Accept it:  accept that it is what it is, and there no other way it could be, wishful thinking will not make it go away or change what has brought you to this moment.

3) Deal with it (effectively):   respond to the situation, don't just react,  do what will work or if it's more effective do nothing.
