Dont' get too down on yourself Scoot! We all miss at times. It was prob. your first shot in the field while hunting with a bow too so nerves are going to be very high. I did the same thing you did about 3 weeks ago or so, (its my first year too!
but my arrow went below her instead of over her :/ she took off and i lost her in some brush about 30 yards away. I totally rushed the shot, i was shaking and so nervous (i can't imagine how i'll be if and when i ever get a chace at a buck!) i should of tried to calm myself down, she was on a b-line to the acorns that im hunting and i freaked out thinking i wouldn't get a shot. Then when she stopped broadside to eat i shot immediately, it was about 25 yards, which i feel comfortable with, it is prob. my max i would shoot though. It was so stupid on my part, i should of waited and took my time, but i didnt, (lesson learned) and to make it worse i havent seen another deer when hunting since then :/ but like you said just being outdoors is great! And getting to just see deer is a rush! Don't let it get to you, there are many more deer out there, ya just gotta be patient! when i missed it made me more determined than ever to get a shot at another doe or even better maybe a buck! Keep hunting it's a really good way to forgive yourself for a missed shot!
