Good Day Sir..
Rest assured we all take our turn at being a Dumb*****.. I have even been known to but in line..

but your troubles are easy to repair..the posted methods for removing the stripped blind nut will all work.. I usually just put in a screw from the front end and give it a solid hit with a ball peen hammer and that seems to work as well.. I hope you didn't seriously hurt your hand..
PS: I work with aircraft and I have done everyting from drill through my finger (yeah ouch) to grind off 98% of my finger nail..with an air powered dremel. (Thank goodness it grew back) I must have been butting in line that day..
Enjoy your 4 Star..
