Lilangel, maybe you have social anxiety disorder, and that's why you get them in crowded places. I was terrified of people, I couldn't even go into a gas station by myself, let alone a store!! I also couldn't even call people I didn't know, I had to have my mom call my Dr. And set up all my appointments, and even go to the appointments with me, even though I was 18, married, and not living with her.
