Why do I feel so lonely?

I have so many friends that love me--
no, like me--
no, tolerate me,
And I'm completely surrounded by people
all the time.

My mind is convinced that nobody actually wants to be my friend.
Don't get me wrong, they're all really nice.
But it believes that they're doing so out of sympathy,
pity.
I'm not really an interesting person,
I always overanalyze situations so that I can say the right thing, but then I get it wrong anyways.
I mostly just make things awkward because I have no idea what I'm doing.
I'm kind of just annoying, really.
I wouldn't want to be friends with me either.

So why do I feel so lonely?
It's not because I'm alone,
It's not because of them,
It's because of me.

There's something wrong with me.
