It is amazing to me how quickly the drama ends when you just stop participating. That of course is easier said than done because most of us are so emotionally tangled up in it that we can't let go.
No matter how hard we push against something it is not going to give way, it is usually just the opposite.
You don't have to stop caring or feeling something about the situation you just have to stop reacting to it. Focus on something good, anything to get your mind off of what is upsetting you.
A battle can only continue if both sides continue to fight. The war ends the moment that you just stop.
