Woo Hoo! Way to go! I hate those "super stores" too. As soon as I walk in, I get that anxiety blindness - where everything is blurry and disoriented. I always have to force myself through because I just don't have time to come back. I've learned that if I keep motivating myself while I'm there it really helps. Then, when I get out and I'm sitting in the car, I feel proud of myself because I did it. So, I totally understand your feelings on this.
I am so happy for you - good job!!!
