Not sure what to do.

As a tank, I'm usually the centerpiece of any and all screwups. Most of which end up not being my fault!
Anyone who mains a tank and has played with people they don't know, or even those that play with friends, I'm sure would tell you that DPS generally have the most lenient roles in the game.
If anything, use the criticism, even if mean spirited, to better yourself. I wouldn't be the tank I would be today if it weren't for the enmity we generate from our peers.

I am pretty sure this game is very fair when it comes to making sure it is not ALL the tank's fault. There are plenty of different check, on healer or tank, but a lot of endgame content is DPS check, DPS need to kill adds, DPS need to deal with mechanic, DPS need to click something, DPS need to avoid AOE and watch the tether, and go run between orbs so healer not getting hit. DPS has a lot to do, but derp dadidumb DPS think it is so easy to play DPS, ignore all the mechanic, can't dodge anything, random buttons masher, and failing the raid over and over cuz their DPS is far too low. Somehow it is the tank and healer's fault... amazing.

As an aspiring tank...I agree wholeheartedly.

But yeah, the essential problem is that mean criticism hurts so much that I damn near drive myself nuts trying to be awesome in order to avoid it.

That's the spirit! It's pretty much what I did as well. Yeah it kinda sucks everyone won't suddenly be best of friends, but in the end, you're bettering yourself and becoming a great player.
