Why is queuing for ranked so terrifying

Honestly, if people are in the same tier as me, we should all be around the same skill level, so we shouldn't even really know who's doing well or not until the game's over, but I'm just so scared of someone flaming me that I can't bring myself to start a match T.T Everyone says flex queue is less sweaty than solo queue, so I thought about trying that, but even that feels so scary and overwhelming... I mean, I'm gonna do it eventually, but I've been telling myself I'd play ranked since this afternoon and I still haven't queued up yet
