Why am I afraid of talking to a friend through Facebook?

[I state the obvious.]

yesterday we hung out all day long.
we get along really great.

he even listed me as his brother on facebook, and we're not, of course.
i was going to comment on it but i was afraid for some reason and i still don't want to... but i WANT TO!
and yesterday i talked to him with no problem.

what the hell is up with that?
and i put this on the mental health section because it's this weird fear of talking to him that came up for no reason.

do i have a problem or something?

Just go ahead and talk to him on facebook and comment on his posts! Since you both get along pretty good, what bad things would even happen? Think about that. I don't think you have a problem though. If you think you do go to a psychiatrist.
