You have target panic. Nothing to be ashamed of as I bet almost every single one of us has had a touch of it at one point or another. Some worse than others. If you shoot long enough, you'll eventually come down with a case of it.
As other said, the blind bale shooting will really help. As long as you stick to it.
I had an issue a couple years ago where I could not, for the life of me, bring my pin down into the center of the target once I settled into my anchor. Now, I shot well since I just ignored it and concentrated on what I wanted to hit and not the pin, but it bothered me enough that I did a lot of blind bale shooting where I would draw, force the pin to the center of the target, relax there for about 20 seconds, then let down. I'd do this 6 times before I would shoot one arrow. Then I'd do it again until all 3 arrows were gone.
It worked well the problem is behind me now. However, I still perform this exercise regularly, just to keep my demons at bay.
Using a pure back tension release is a definite way to work on target panic. However, if you're a wrist strap shooter only and have no intention of getting into target shooting, it just may compound the problem. It did me. I went to a BT release to help with my above problem and it really made this worse.
