i got target panic so bad three years ago that i almost gave up bow hunting. a buddy told me to practice drawing and find a spot on the target.... close my eyes for a few seconds.....open them to the spot again....let the bow down. repeat this several times. it calms you down. after doing it 3-4 times, AND after you have closed your eyes, open them and release the arrow.

after doing this for a few days, i was ok.

hope it helps you, too!
