I know how frustrating it can be to not kill your first deer. I started hunting at 16 and didn't kill my first till I was 22. I haven't missed a season since. The first is always the hardest after that it gets easier.

Get some shooting sticks thaey will work wonders. I am horrible at shooting off hand so I made my own shooting sticks and I can tap a two inch target at 200 yards with ease now.
