I shoot a recurve without sights, so my potential to miss is inarguably greater than yours, the difference is that I don't lose my mind over a bad shot or two. I refocus myself on doing the shot right and move on. Missing is part of hunting, it happens to everyone, get over it and move on. Obsessing over it isn't helping, stop focusing on what you've done wrong in the past and focus on what you do right. Stop thinking and just "become the arrow", your problem should disappear all by itself.
