#1. get close to a butt target (like 5 ft) draw, aim, and then close your eyes and shoot. Do it over and over. Feel the bow, the release and the follow through.
#2. if you are getting panic shooting at a bullseye, aim just below it . . so your pin is just below the bull. I shot for years with my pins set this way and it worked great.
Target panic is your brain freaking out wanting to get rid of the arrow, but out of control.
#3. Draw the arrow back, aim, and then let down. Make sure you control the release, not your emotions. Do it one out of every 2 shots.
Target panic takes a while to get over, but if you do these things and practice them for a couple of weeks . . . and then keep going back to them occaisionally to keep your brain honest you should see great improvement. There are no magic pills or quick fixes. It takes time and effort. STick to it and good luck.
