> This comic seems aimed at tone-deaf people trying to get others to stop catastrophizing

Funny, my read was that the author is on the side of the catastrophisor, 'this is what your unsolicited advice looks like - you don't understand what a catastrophe the recipients in'.

Nobody ever gets a chance to give advice to someone falling off a cliff or getting hit by a truck. Isn't it the comic itself (at least) that's doing the catastrophising?
