I always thought practice makes perfect, It might be a benifit for you to practice shooting a few more deer.. If you have doe tags practice with that.. Talk to yourself, take a deep breath, and let the arrow fly... It almost sounds like your not only getting a little of the fever but you are questioning your ability to to shoot at the deer.. Try to forget about all that and just let the arrow fly!! Have a little fun with it and maybe it get you over the hump.
