Is It Just me???

Or have just ALL of my games had trolls in them who give up after first blood (mainly botlane)???

I was ranking up fine until I got into my plat 5 series games and then all of a sudden my wins just plummeted. Fair enough sometimes it was me but nearly all of my games have been lost because of trolls and toxic players.

Or is it because it's near plat elo and it happens there?
