I also agree with the above posts
I also know that its tough to suck up but it is something that you have to do!
You know from reading about your concern it just proves to me that you are an ethical hunter and you deserve another shot!
I know that it is a sickning feeling but you cannot dwell on it
Unfortunatly sometimes this happens But don' t feel that you should stop hunting
Like said in the above posts learn from your mistake and next time you will be sure to be successful
