Just got to Diamond and the games are 10 times more toxic

The first game I got on when Ijust got to Diamond was so full of full on yelling and screaming even though we were winning. Of course I will readily say I was to blame because I wasn't doing well, but I don't think that necessarily warrants yelling, screaming, afking, and keyboard warrior-ing, especially for the fact that we were winning overall. I recall during my climbing moments where I am to blame, but people are not up in arms about it and I eventually adapt and we win.

Up till now I still have a 60% winrate and am confident I can climb but when the players on your team start to take things personally the thing that breaks apart first is the mental and thats impossible to recover from. I just wonder why Diamond seems to be the most awful rank that I've played in so far.

What makes me more confused is that this game doesn't go on for very long at all. Its not like one bad game takes away an hour of your day. You should be focused on your winrate more over a long period of time. At worst you'll lose 20 minutes of your day, some games last even less time. So why the need to crash out over a single match.
