ahh man. That sucks bings.
I had it for the longest time. Grew up with it. Thing about this stuff, it never TRUELY goes away. I battle it all the time, it runs through my head every shot, but I win.
It's best to have someone with you.
Eyes closed, at 7 yards, pull back, visualize what you do, have the other guy make sure you are going to hit the target. Let the arrow fly. This exercise , is nothing more than doing the opposite of what target panic is -- the fear of missing. You are shooting with your eyes closed, trusting the aiming, and visualizing what you do, without visual aiming. Shoot a few arrows doing this.
Next, open you eyes. Pull back at 7 yards, hold the pin on your spot, let the arrow down. If you release the arrow, target panic wins. Here is where you need to work it out of you. If it's bad, ducktape your hand to your release or string.
You HAVE to be able to hold that pin on there at close distances and be able to let down. Move back to 10 yards, then 15, etc... Spend the time at each distance until you are able to hold that pin on your spot without releasing it, with confidence.
Everyone that has had this, seems to have a unique case of it. The thing that used to get me is shooting in open spaces .. such as fields. A target in the open field, I was in trouble..
All else fails, go to the doctor and get some anxiety medicine. Afterall, this is ALL about conquering lack of confidence.
