Get close to the target (a couple yards) and shoot with your eyes closed. The goal is to concentrate on perfect form; draw, release and follow through without the distraction of aiming.

It sounds like what you need to do is just the opposite. You need to lock the trigger down on your release and practice aiming without shooting. If there's an adjustment screw on your release, crank it down all the way so that the release can't be fired. Then draw the bow back and concentrate on holding the pin on the target as you go through your mental shot execution sequence for say 5-8 seconds and let down relax, breath and do it again. Repeat it a few dozen times and add 1/2 dozen each day.
