2 years ago I went 0 for 7 on deer. That sucked!
It was MY FAULT! I had not practiced as much as I should have and missed. Thankfully I did not wound any of the deer, all clean misses.
At the end of that season, after a fine meal of "tag soup" I vowed that would never happen to me again.
I started to practice once per seek for about an hour or so at the local range.
Last year I was 3 for 3!
This year I have missed one deer but that is the only shot I have had.

I do not know how long you have been bow hunting but it took me 5 seasons to get my first deer with a bow.

Keep at it
Realize that the missed shots are your fault and do something about it.
Welcome to bow hunting, if it was easy, anyone could do it.
