Where did I go wrong

I remember a time when I logged onto league to have fun. I remember a time when I tried to help people who made mistakes Where did that time go? Now whenever I log in it's more like "Oh god league yes, cause I want to deal with toxic jerks and feeders." And now looking at it I'm toxic, I've started down this path, I belittle people for their mistakes and I bm people when I beat them. What's happened to me? I never wanted to be this way, I never wanted to be the problem. It started from trying to tell people how to improve. Now it's twisted into something sick.

What's wrong with me, why can't I stop... Send help
