What is wrong with this Community?

I had to leave a game just now, probably will get leaver penalty for it and that's fine as I won't be returning. I had picked Xin Zhao and helped bot lane get a kill within the first 3 minutes and that was the only happy point in the game. After that I decided I'd pick up Devourer and build Tank, that didn't happen.

I was farming Jungle and the Alistar started getting mad asking why I was Jungling even after giving his lane an advantage so I thought i'd pop my head in again and got countered by the Skarner who killed all of us and that's fine. I was then behind and decided to get back to farming poking my head in mid lane every so often as the Xerath wasn't far ahead and hopefully be ready with Sated Devourer before 30. As time went by Alistar kept calling more and more shit on me and they started teamfighting quite often even with most of the team behind.

Fast forward and its 30 minutes i'm 1/9/10 and Now Darius starts in on me asking why I wasn't Tanky yet. I explained I couldn't get farm we were having to many failed fights but it fell on deaf ears and they proceeded to talk down to me. I'd had enough and I told them to "F" Off and to not treat others like that and left.

Now i'm a 21 y/o man with a wife and baby but even this just hurt my feelings and couldn't take the stress of playing anymore and had to vent somehow. Thanks for Reading

(P.S)I know I could have muted them but I hate that that's like putting a bandaid on a scar it hides it but doesn't remove the pain or emotion attached to it.

TL;DR Had a Bad game Teammates ridiculed me I left.
