It's not defeat bro...
My wife has bp--clinical level--so I can relate and sympathize.
You're shooting too much.
It shouldn't just be about becoming "proficient", at least not for some of us.
It's about "me time", relaxation, enjoyment, and overall personal "wellness".
If things are really "bad" for me, I can't shoot worth a darn either...and with bp, you know what a downward spiral is!
So don't give it up! But do back off a bit...grab that bow maybe twice a week and shoot three or four arrows at about 15 yards, two or three times, and then STOP!
Good bad or decent shooting, don't get overly frustrated with it, don't dwell on it, and don't let it get ya down!
Or you can even try and make it fun...throw an old ball around the yard and poke a judo or two at it...or a piece of fruit, etc....
That should also give your finger time to heal; if not, it will only get worse from the repeated shooting stress...
So slow down, or take a break, but don't give up...
PM me if need be...
Take Care,
Marc
