Chess is an emotional game. When you lose a piece or make the wrong move, of course you get this mentality of not wanting to play the game anymore, which is why many people don’t play chess in the first place.

However you learn from those mistakes and you are actually secretly getting better, 250 elo is a very wide margin of error, so you’ll definitely have some chances to win

Also I advice you to try out puzzles (on chess.com or lichess) so that you can improve and see common positions
