progressively getting worse

Thank you guys for the responses, as for the advice, I do look over my games after playing them, but in the game mentioned by response #4 HeckinSprout, I obviously didn’t see the fork, and even if I did, when I looked over the game in analysis white can play Qe3 and then taking the forked knight is a losing mistake because whites queen, other knight, and bishop get an attack on my king. So even if I did see it I would still lose. You first have to first trade off other prices before taking that knight is safe. Besides that specific game. Part of the reason I resign when I make an error isn’t just about anger, it’s also me trying to be practical, I don’t want to spend 20 minutes on a game that I have a less than 50% chance of winning, just to lose. So why humor a lost cause? And even if I do win, it hurts to know that the win was “undeserved” ie: I only won because my opponent didn’t capitalize on their advantage. But I suppose I’ll try to be a bit more “tenacious” as one response put it, but still, blunders make me feel stupid and not want to play.
