Here' s how I look at your situation. First of all I give you 1 million pats on the back for attempting to take a turkey with a bow. Turkeys are the hardest animals to hunt all together not to mention with a bow. Kudos to you.
Secondly it sounds as if you just missed the bird and what they hey, we all miss sometimes, even the pros. Dont let it get to you. And yo udid the right thing by taking a look around after the shot for blood to see if you did in deed get a good shot off. I wouldnt spend too much time worrying about the tom that got away or the one you missed just go back and try again, and be patient, an arrow doesnt make as much sound as a 12 gauge he may have come back for a second lethal shot and he may have kept going, well never know till you get him, hes still out there. good luck to you in the future and dont get discouraged with a bad shot, again, we all make them.
