Having bow only hunted for 21 years (over 1/2 my life) I've lost track of the number of whitetails I taken with a bow. Well over 100. With that said I still catch myself on occasion falling completely apart, heart racing, short of breath. To tell you truth it's a catch 22 w/ me as i don't want to become "mechanical" in nature as it did w/ a firearm or compound bow. That feeling coming back to me is what I never forget about the 1st doe i shot w/ my recurve 7 years ago. I dang near shook myself outta the tree that evening..LOL The situation, not the animal seems to bring on my panic attacks. Weather more than one deer is there, is it alert, etc.
That being said...the only thing that helps me in those times is talking to myself....I mean REALLY talking to myself...lips moving and all.LOL I make it no diff than when I'm standing out front or in the basement shooting when I discuss my form, release, and how bad my shot was w/ myself. I just say...breath, breath, now...look right there...there....she's gonna step...draw...pick...release...
Sounds like a funny thing to do, don't know when i started doing it, but it works for me.
Typing this makes me want to call my sychiatrist.....
