It's so difficult though. I used to blame anything or anyone but myself for problems in general, and realised that was a toxic way of thinking. LoL has helped me get out of that habit, but now it seems I'm in a different one, where I just assume everything is my fault. :/ It's like being stuck in limbo - I don't want to blame others, because I remember the old habit, but I don't want to blame myself for everything because that's stupid and self-destructive.
Man, I wish this game was the only thing I took too seriously. I could just quit, then. >.<
EDIT:
That's one thing I've gotten way better at - defusing/trolling ragers while not internalising what they're saying. 'Ooooooooooooooooooooooooooooh' in all chat when they make a mean comment, or something specifically calling them out on a homophobic slur, always goes down well. Or badly, depending on how you view it.
