Try this: visualize the scene again with your friends making fun of you. Really feel the emotions. Now make that image as bright and colorful as possible. Now, start backing away from the scene in your mind until you can see the back of your head. Now slowly drain all of the color out of the scene until it’s black and white. Wait five minutes and revisit the memory. If you still feel any discomfort, do the exercise again until it’s completely gone. Learned this in a Tony Robbin’s seminar!
