Follow the EMDR bouncing ball with your eyes, keep your head still. The back and forth eye movements engage the parasympathetic nervous system to calm / relax the sympathetic nervous system (responsible for the flight, fight, freeze response). I can also recommend you think about your goals as you 'keep your eye on the ball'. It will allow the repatterning of any unconscious anxiety you're holding about those goals. Consider making this a daily 5 minute practice. Here is a link to an animated bouncing ball, its speed & color are adjustable.
