No matter what channel or mode you choose, remember to keep breathing while you feel your fear. Continuous breathing is one of your body's best tools for integrating emotion. Another tip is to imagine that you're surfing. Pretend that your fear is a wave in the ocean. Waves form, crest, break, and dissipate naturally, as long as nothing interferes in their movement.
Fear is the same way.
Let it move through your body like a wave through the ocean. Tremble, shake, scream, cry. If you want to learn more about fear, find a way to catch one of its waves as it crests in your body. Use your safe channel like a surfboard to keep you afloat. Practice riding your waves of fear whenever they arise.
