Stress Shopper

I'm not a stress eater, drinker, pill popper, or any other stress related vice-haver (I think I made that word up, huh?), I'm a stress shopper. Ugh!
Yesterday was a horrible, no good, very bad day. On my lunch break I had to leave the office (I often don't, there's no temptation to spend if you aren't somewhere that allows you to spend). I was driving down the road when I realized exactly where I was headed - Target! My thoughts were:
"I 'need' some new pants."

"NO, you can wait on them."

"I 'need' new shoes."

"NO, you can wait on them too."
"I'd love a new purse."
"NO, you just got a new purse, that you love."

"I can go get Kasen something!"

"NO, Kasen doesn't need anything."
"I can just go look."
"NO, if you look, you might be tempted to buy - you're just stressed, keep driving!"
So, I did. Then I decided I NEEDED a drink from Sonic. No, a burrito from Taco Bueno. No, some fries from Chik Fil A...

I ended up getting some fries, a sweet tea (yum!), and a brownie from CFA. It didn't make everything better, but it helped.

I wonder now though... I have admitted that I have a problem, which is the first step (right?), so what's next? How do I avoid stress shopping? There's always gonna be stress you know.
