Did you ever have a fandom (any kind, game, movie, series, book, you name it) which really affected you deeply? Either in a positive or a negative way?

Personally, I am easily moved by a lot of things but it doesn't necessarily affect me for a long time. But then I played Persona 3 and I got the big ending spoiler. I already was in a mildly depressed state at that time, so the game probably wasn't the only factor in this, but it somehow hit me really hard. I haven't managed to play the end of that game after that and I don't plan to for fear of dropping into that ugly black hole again.
