Eighter try lighter draw weight and see if it makes a difference, dont worry we wont bash you for not being able to grind your teeth when you draw.
Sometimes it could be an issue with you draw lenght eighter to short or to long and is not comfortable for your muscles to relax, and my third guess is your grip .hope i dont get banned for this but when my uncle thought me a few years ago is to hold it like it was the thing between your legs im sure you dont put a death grip on that.Try to see if any of these things are a issue first and then see if its something else like target panic maybe.
good luck hope you figure it out soon .and like salukapiv said eighter lightly circle your target or like some people in my area is to have the pin on the side of the target slight and dont have the pin right in the center of the X
