RE: worst case of target panic ever!
Not possible for you to have the worst case ever.I am quite certain I had it! A few things you can do to break the spell.Blind bale shooting (google it)not caring so much (meaning relaxing)you have to remember that you don't have to shoot,let down if you aren't under complete control.
If your malady is as bad as mine was,you will get professional archery instruction,change your stance,shorten your draw length dramatically,go to a back tension release exclusively for three years(including hunting).
If I had any one recommendation it would be to relax and not caring so much,with a relaxed mind and body you can make the necessary adjustments to conquer it.
