Every since I was younger I have had these attacks. It is like a sudden urgency and an increased intensity of my senses. It starts off with me concentrating in a quiet and controlled environment like taking tests, folding laundry, or video games. It starts out with a subtle feeling in my head, then a buzzing, like a crowd of people all chattering until I cant think. Soon sound intensity like a ceiling fan or typing. Then my hands feel weird and suddenly everything is urgent and loud and fast.
