What to do if you blundered your queen

If you blundered your queen for a rook, it's preferable to resign but you can continue.

If you blundered your queen for a piece, no you can't even continue such a waste of time.

But if you blundered your QUEEN for nothing in return, or mouse slipped then you continued playing ---> you have to check your mental health.

Yes, but what if my opponent previously blundered their queen?

Two queen blunders at 1500+ elo? show me the game.

I remember a game from chess.com, where our hero blundered the queen and instantly rage-resigned. He was still up a full rook.

if u blunder ur queen then awaken the kaiju within u and capture his queen then spam l in the chat and resign or just resign really
