I have a problem with social interactions and was wondering if I had a problem. I googled all the problems I could have, researching and reading a lot of information about them. HFA sounds like me, but I don't know if I do have it?

Things I've noticed about myself that is abnormal:
1. I read all day, every day, for at least 6 to 12 hours.
2. I dont like any kind of lights on in my room.
3. I pace around repeatedly for hours while reading uncontrollably. I sometimes don't even notice I'm doing it.
4. When I find a new good song I play in over and over again for at least 2-3 days.
5. I hate any sound as loud as someone talking loudly. It feels like as if you stared at the sun for a second, extremely uncomfortable but not painful.
6. I don't have any friends because I don't like talking to people.
8. My mom says I look aloof and doesn't care about anything but I do care. I just don't like to show emotion.
9. I feel more hurt than normal people when I'm misunderstood or insulted.
10. I don't like to change what I eat. I eat the same things every day until we have something else I like. I would rather starve than eat anything else.
11. I have excellent grades in orchestra and math class, but below average grades for history and science.
12. I feel nothing for anyone besides my mom and sister. When my uncle who I'm a little close to died I didn't really feel anything
