"this frozen fear in my body"
Keep saying these words (substitute shame, guilt, whatever suits) and tap on all the points. You will most likely find that strong feelings will come up, keep tapping and breathe right into the centre of the feeling. Maybe memories will not be well defined, but the energy of the feelings encoded along with the memory in your brain will be felt. Just keep tapping and breathing through whatever arises. If you feel the urge to run or avoid, notice this and continue to breathe and tap. Tapping like this will loosen dense energy and help it to start flowing again. Keep going until you feel you have processed enough and feel relaxed. You can always return to it at another time if you feel the need. Tapping diagram.
You can, if you like, name a body part that you know you have an issue with. For example "this frozen guilt in my large intestine" or "this frozen grief in my lungs" etcetera.
