Then try recreating some of these sensations when you are in a safe environment.
Take a few minutes to brainstorm the most common sensations you feel when you are stressed — butterflies before a work presentation, breathlessness when you are flying or shakiness because you are overwhelmed. Then try recreating some of these sensations when you are in a safe environment. For instance, you might bring on sensations of breathlessness and panic by slowly spinning in a circle for a minute, then intentionally hyperventilating, rapidly inhaling and exhaling for a minute. Let yourself feel the sensations for a few minutes, then repeat the next day for several days in a row.
