I mock it. Poke fun at it. It wants to pony up one option? I can do better :D Helps me put things in perspective.
Random example: It's all gonna end in tears gets trumped with bloodshed, plague, loss of life & limb, angry mobs, leeches, asteroids hurtling from the sky, etc. Or: and my eyeballs will fall out, and I'll be blind with a too short seeing eye dog who doesn't like me (suicidal beagle, most likely), trapped on a bridge...Lol... The possibilities are endless.
The itty bitty shitty committee is all about losing perspective. Making this one thing seem huge. So I smack it down with some totally bizarre never gonna happen consequences. The feelings the critical voice lays at my doorstop are just as ridiculous. So I like to fight fire with fire. All of a sudden I can laugh at myself. Okay. So you're ugly, or stupid, or whatever. Not that big a deal.
<grin>
You're ugly.... Children will cry, and mothers run screaming. People will in fact turn to stone and melt like wax. The earth itself will groan in protest, streets bucking, buildings collapsing.
You're so f*cking stupid you can't even fill out this paper... Which means the people at the Nobel Laureate committee will undoubtedly commit mass suicide in grief you will never be able to join their ranks. You're 3rd grade teacher publically apologizing on the news for how she failed in her profession.
