My mom hates to go shopping too! She can't stand the crowds and line ups!
I, on the other hand, find shopping is a very pleasurable and relaxing experience for me.
I only ever go to the mall alone, and that way I can spend as long as I want looking at everything I please. I can walk at my own pace, and it gives me time to think about things, when I'm stressed out.
You should try going alone, take an Ipod, and spend a few hours on your own, doing your own thing
It really isn't as lonely as it sounds, and it's less chaotic that way!
Sorry if I'm not much help!
