Adams, I can relate to the feeling. I think we all can. One time my buddy shot at a small 6 pointer broadside slowly moving left to right at 40 yds.(which he is very capable of making) and the deer jumped the string so bad it was able to turn itself around before the arrow got there. We waited 1 hour and followed a very easy blood trail for quite a distance (about 200 yds,) and found him very dead with an arrow broken off in its left ham severing the femoral artety. He was very upset that he hit the deer in a place that he wasnt even aiming for let alone the opposite side.
It took days for us to convince him to be proud of taking that deer.
Its hunting not shopping and a if things could go wrong they probably will.
Cheer up you got your deer with a bow and that in itself is quite a feat.
