Shooing is GREAT therapy! Whenever I'm stressed out, I headfor the range. It's a geat combination of focus, and absolute agression.
I'm also a golfer, and yes, each squeeze is like each swing. You have to forget about your last shot. If your last "flier" is on your mind, on the course, or at the range, your next shot will suffer.
What I'm really looking forward to is taking my XD 45 north with me to NY and shooting there, in the wide-open spaces. My Uncle has a gong-range or steel plates. Nothing beats lead-on-steel for stress relief...
