Knocked down or bowled over by a nasty or disparaging comment from someone you thought you could trust, with damage to your reputation or prospects.

You try to catch it, but it’s way more than you expected, and it knocks you flat on your back. You feel like a fool for being knocked over and for trusting that person in the first place.
