<human>: Can you provide a brief rundown of the text in within 3 sentences?

I know in the grand scheme of things this may seem like a petty question, but I have a friend who has undiagnosed social anxiety. He's 26 and has been one of my best friends since I was 12. The problem is that I just got a job in a city about 2000 miles away, and he has subtly hinted at not being able to take on the outside world without me there.

He is constantly worried about going out in public with me and as of late, has pretty much given up on socializing in general. He has never been that outgoing, but recently it seems that he would rather shut himself in entirely than risk making new friends and "embarrassing us" as he put it. He is very very awkward to be around. He never knows what to say, always makes untimely jokes, never makes eye-contact, fucks up handshakes constantly and is just an overall weird person to be around... In PUBLIC. Behind closed doors he is the funniest, most sincere and amazing human being I've ever met. I wish others could see him for the truly awesome person he is instead of the weird, nerdy, skinny kid with messy hair who told the awkward joke at dinner.

This guy is like a brother to me, and I really want to help him, but I have no idea where to begin. I've read about successful treatments through coaching, on the web, but I don't think I would be able to convince him to visit a doctor.
<bot>: My friend is an exact replica of the socially awkward penguin and I want to help him, but I don't know how.
