All you can do is apologize to your friend and his mum and say you didn't realize you'd react to the alcohol like that. Hopefully they'll understand.
James, this bit by HurtLoam is all you need. If they're friends, they'll understand.
I know it may seem devastating--the shame-gene seems to be quite active in us--but from an understanding, non-drinker it's not that bad. I've seen drunk people do far, far worse. The bloke yelling at you was likely piss-drunk himself, and also probably only vaguely remembers the events, if at all.
I don't know the details, but I think you're fine. Just call your mate & explain, and ask to talk to his mom and personally apologize to her, as well. She'll love you forever; it demonstrates high character. Odds are she's not offended, so the apology can only win you more points in her eyes.
Good luck!
