If I'm reading your post correctly, you are having trouble bringing your pin ALL the way up the your intended target? If this is correct, you are in the beginning stages of target panic. Here's what I have used and have taught over the years:
What's happening is you're panicing about holding steady, and as part of that you feel you cannot aim at the target, and you punch the trigger and/or realese BELOW your aiming point.
So what needs to happen is aim directly at the bullseye and just sit there (do not release), if you cannot hold on the bullseye, or are shakey, let it down. Tell yourself your are NOT going to release the arrow.
Because you have no intention of pulling the trigger or releasing you do not panic about the fact you are aiming. With practice you should become used to the fact that you are aimed at the bullseye, thus, training your brain this new learned process. It's ALL mental.
After you have mastered this level, begin to rest your finger on the trigger and simply aim. If no problems exist, remove your finger from the trigger, and let it down again. Complete this cycle over and over. The more you do this the better and more steady you'll become.
Next, without a bullseye (target) start blind bale shooting from about 5' away. Draw your bow and get steady with your eyes shut, just feeling form, and work on a proper realese. Now you should begin to have a good panic free release, and the ability to aim at the target.
Once you completed the above techniques, begin to shoot at your bullseye at close ranges. (so you are shooting at a HUGE bullseye). If you are shaking, immediately let down and don't consider punching when your pin "floats" into the bullseye. Simply re-do what you've learned until you become steady. As you master the short ranges, move to longer distances.
As I said it's a long process, that must be commited to early on to eliminate and/or conquer.
Hope it helps and good luck.
