Star Tiger - Hypnosis is not magic. Hypnotherapy is not the same as stage hypnosis. A competent hypnotherapist will ask what damage you consider the GB has done to you?
What you want your new life to include?
What you are willing to do to achieve those goals?
He or she will listen and help you to be aware of your emotions and what has caused them. Then help you to accept and move on. It takes time and can be both revealing and disturbing. We change when the pain of staying the same is greater than the pain of changing.
