I can certainly understand the Post Tramatic Stress Disorder, I would have been the same when I was younger, ( old guys have built in excuses )I'm here for you if you need to talk, and we'll go to the range to work on your shooting and make up a good excuse list so you will have one ready in case this happens again.
It will take some work but we will get your Macho back!
Come to IDPA at PSC tomorrow and you will see a lot of us embarrassed and looking for excuses.
