no matter how much anime you watch it wont replace real friends, anon
Osomatsu-san. Currently airing.
Calling it SOL might not be 100% accurate, it's more of a comedy skit show.
Wakako-zake.

Trailer Park Boys. OK, it's not anime, but it's the closest thing I can think of, and it's a damn fine show. Easily one of Canada's greatest cultural exports in my opinion.
Things that might come close in one way or another, since your request is very specific:
>Genshiken
Bunch of college-age Japanese geeks living their geek life.
>Uchouten Kazoku
Young adult shapeshifter racoon(s) and some other mythical characters screwing around.
>Barakamon
Neurotic guy gets sent to some village with a super chill population so he cools off.
>Shirobako
Young (and some older) adults in anime production having stress and resolving it.
Each of these will make you grow as a person.
Well, there's a manga about Japanese adult women drinking beers, it''s called Nomi Joshi.
