People with Asperger's, how impaired were you as a child and are you better now?

When I was a child I had no friends. I think my first friendship was at 12 years old. I spent recess reading or thinking to myself. I used to scream when people touched me and freak out at loud noises, strange smells and scratchy fabrics. I took most things literally and I was often made fun of without even knowing it. I only talked about whatever my current obsession and if someone tried to talk about something else I would attempt to change the subject to my obsession. At one point when I was about 10 I got obsessed with human decomposition and creeped out a lot people by only talking about rotting bodies for about three months. I had no idea that I was frightening people. I currently am not that badly impaired. I still can get very confused in social situations and am somewhat scared at large social events but I do have friends. I can even go to metal concerts and participate in the mosh pit and everything but I don't think of it as a social event. I still freak out at certain smells though. I can talk about subjects outside my current obsession though I do sometimes have a hard time not talking about it. I still sometimes frighten people with my vast knowledge of serial killers though.
