Hmm. I'm pretty much scared of any social situation, really. I get nervous talking to everyone, even family or old friends. Even being out in public and not saying/doing anything is very nervewracking.
When I'm particularly paranoid and/or have been having a lot of nightmares, I become afraid of the dark.
I'm also scared of storms. And bugs. Those are more common.
I used to have that exact same social situation fear. You'll grow out of it ^-^
