Why am I unconsiously swaying back and forth?

Trying to figure out what is going on with me. Several weeks ago while out to eat my husband asked me if I was aware what I was doing. Not knowing what he was referring to I come to find out that I sway or rock back and forth white eating and driving, and it is not to any music. After doing some research I don't think it is ADD or Autism but I do have a few other unique traits that people have commented on. I have extremely sensitive eyes, I own way too many sunglasses and sometimes they can't help me. I cannot touch cotton balls; their texture makes me cringe. Am vegetarian who eats bacon, because most meat's texture grosses me out while bacon is crispy. I eat my cereal dry; I do not eat soggy foods. I can read other peoples expressions, however I have a hard time sympathizing with people whether they are happy or sad, I am uncomfortable. I often fumble with my words, like my mind isn't moving fast enough for my mouth or vise versa. At one point in every conversation I say "sorry I can't talk today" to try to play it off as a joke. I am sure there are things I am forgetting, but any suggestions as to what is going on? Why am I swaying in public and how do I stop? Or am I just weird and none of this has to do with anything? I am a 29 year old otherwise healthy female.
