In the context of stress, this word, action and strategy can be your best friend! As we attempt (that is if you do) to turn down the dial on the periodic pressure cooker of stress in any part of your life, you need "go-to" practices and strategies to do so. When offering help in any situation I like to have a toolkit of options. One practice I recommend you have in your toolkit is the ability to surrender.
In many ways the opposite of surrender is resisting reality in that moment. It's like throwing an internal, perhaps subconscious temper tantrum, in which you're saying, "I don't want this to happen, I therefore refuse to accept it and to show you how much I don't like it, I'm going to react in all sorts of ways that can hurt myself and others."
