I've tried hypnose therapy for stuttering with positive results (only temporary). The hypno therapist could aim to replace your discomfortable feeling into a happy feeling (that you had when your brother had a birthday). The hypno therapist could aim for creating a new personality (acting as if). A mentality where you don't look back on incorrect thoughts. He will also explain that negative thoughts are not the same as incorrect thoughts that maintain the downwards mentality. The hypno therapist will usually use visual tools to ask you if the incorrect thought or feeling is warm, cold, big, small, has a color and will ask you to make it smaller, in black-white or put in a box. Shock therapy aspects include going against your expectations while visualizing a problem, then the hypno therapist will ask you questions if you are feeling sad and learning that it's not actually a problem. He can then say "you feel happy when you are surrounded by people" (changing outlook) or he asks "do you want to avoid or engage" (hypno bind) or he asks "do you want to engage for 10 or 20 minutes" (double bind technique). Hypno therapy could go into body scanning, eye fixation or countdown breathing. Hypno therapy could aim for creating an anchor or trigger (like snapping the finger or a certain I can speak feeling). I would recommend visualizing techniques with your hypno therapist or the rewind technique where you visualize for 15 minutes that you stutter. The hypno therapist will tell you that you are in a cinema watching your old replay. From above you are watching yourself sitting in the cinema. You watch the you (who is above) watching you sitting, watching you in a video replay. You can also try the rewind technique with a friend if you google for "rewind technique".
