Have you ever felt a sudden, throbbing headache on the subway from the perfume of the person next to you? Walking down the street, does a strong food smell or air freshener make you feel nauseated and bring on a headache, making you wonder why you are the only one so sensitive when others seem fine?

Have you ever felt your heart drop in sudden shock at an insignificant noise? If you find yourself more sensitive than usual and shrinking back easily at small stimuli, you might worry whether your mind has simply grown too weak.
