Oh I'm sorry @avant-garde what a frustrating interaction, it sounds as though it has really been playing on your mind.

If this comment truly was from a place of not understanding, do you feel as though there might be opportunity to let them know why a comment like that wasn't helpful given the situation, even if it's just a brief conversation to try to prevent it from happening in the future? 

For now, is there something that you can do for yourself this evening to show yourself a bit of extra care? It sounds like it's been a hard day
