I'm the same. I always have to have my mom go with me. There's always so many people, its so overwhelming. Checking out is the worse for me. I feel so pressured and rushed when people are behind me and waiting. I get so anxious and impatient and freaked out, shaky, hard to breathe, thinking people are thinking horrible things, feel crowded and trapped. I hate it. Its one of the hardest things. I always make sure I do as much shopping in one trip so I don't have to go as often. its so difficult. I feel for you.
