need help with analysis
Hi, welcome to the chess.com. For a start have a break from the live-chess is not doing you much good, go onto turn-based (which you have tried sofar) that will give you more time to think on your moves.
From that diagram with the loss of black queen and you have a very active knight which would give you a very easy game for you to win by moving the kight to c6 then to e7 and start putting pressure on the d-file (with rook and queen) will help your d pawn to promote.
