One of the methodologies in NLP is moving from problem states or feelings into ones of freedom and ease.
Some people will regard this process as chaining anchors others may regard this as collapsing anchors. It can be regarded as both. More importantly it is really all about shunting anchors or states. That is to go from one state to another. This is accomplished by shifting physiology and some Thought Provoking Dialogue.
This is one way to make yourself feel better and let go of the past … while preserving as much as possible of the learnings … so you ideally don’t get into the same kind of mire again. It is also a way through repetition to train your body to shift at the first signs ( often unconscious ) of the problem state to a resource state.
