What disorder do I have?

All my senses have become overly sensitive, I have bent elbows, my face does not show any expression usuallly, my voice is monotonous always, my nickname was robot in my school and college days, I have never liked to hug or touch anyone(even my parents),I used to blink my eyes very hard and frequently in my childhoood, I used to keep moving my shoulders repeatedly in my childhoood, my thirst has now increased a lot- I drink close to 4 litres of water a day, I become breathless for 5 minutes every time I come out of a hot shower, I have a huge craving for sweet stuff- so much that I used to steal my roommate's cookies at night even after knowing he doesn't like to share any of his stuff with others. I have been tested negative for hiv, sinusitis and diabetes.
