Getting destroyed, but finally ... mating my opponent!!

Hilarious low ELO bullet chess. I am very bad at bullet, BUT I really find 1100-1300 bullet players much better than 1800-2000 rapid players. I want to "believe" that I confront many cheaters, otherwise I really have to stop playing chess....Since yesterday I lost almost 200 rating points... In this game you can see why. I got destroyed by my opponent. I lost my queen, many other pieces and was fighting to stay alive... Suddenly, my opponent blundered mate in 2!! I did not see it immediatelly, but since the first move was a check I played it quickly and then my opponent froze... I know the feeling.... Completely winning and playing the only move that loses the game!!
