Looking at your chess.com games, your last 3 games were wins, and looking further back, to find your most recent losses, none of them were in Q+K endgames.
But who knows, maybe your "immeasurable pain" has caused you to go blind or something.
It hasn't made me go blind but it feels like a punch to the gut.
And the games were all on lichess. Tbf to myself in all the three games I berserked and didn't know berserking also takes away your increments.
I just lost three consecutive Q+K endgames
I feel like trash..
