Tapping Directions in Brief:
1). Assess your discomfort level on the issue you'd like to tap on, with a scale of 0-10 (10 being a high level of discomfort)
2). Setup: Using several fingers, start tapping gently on the Karate point while repeating: "Even though I have this problem (be specific), I deeply and completely love and accept myself.
3). Round: Tap gently about 7 times on each point while repeating the reminder phrase about this issue, "this problem" (be specific). The points do NOT need to be precise. Tapping on one side of the body is fine, but both sides are better.
4). Reassess the intensity of the discomfort.
5). Repeat tapping procedure using "this remaining problem" (be specific) until the discomfort is at a 0. Notice memories or different feelings that may come up, and tap on them too.
If your number does not move, drink a glass of water and try again. Or you may be experiences "shifting aspects", in which case pay close attention to whether the intensity has shifted to some other emotion or event. You have the choice to follow the different one or go back to the original.
If you want to work on a particularly intense trauma, I highly recommend that you seek assistance from a qualified professional.
