I know exactly how you feel; my friend is charming beyond all reason. I'm often envious of how witty he is, and the fact that he can befriend just about anyone astounds me. The social struggles are real, eh?
I have a friend like that.
He's similar to me in many ways, probably same personality type, but people flock to him and he's got a magnetic personality.
I just can't do it, even copying him would not work as the engine that drive the repartee is not the same.
Still, he'd suck at a lot of things I can do, so I don't feel too bad about that.
