I am sorry you are going through what you are.Bowhunting will really test a lot of aspects of your personality.It is always darkest before the dawn! What other analogies can I use to cheer you up? Most all of us have experienced similar things either in hunting or other area's of our lives.If you love it don't give up!
Like others have said give yourself a rest for a bit and than go back at it with new enthusiasm! Best of luck!
