Today I was out shopping and in the next aisle their was a man with a booming loud voice, then kids running around screaming and shouting, parents shouting at/of the kids, banging and clattering of staff sticking the shelf. I just felt like everything around me was closing in and moving 100mph, the noise was overwhelming and I didn't know what was where and couldn't concentrate on what I was looking for. I had to move away to calm myself and wipe my tears. This has happened a few times now, is this normal.
