Recently my performance in blitz has been degraded gradually, I know I am better than that but still I play like shit, despite having success in classical and puzzles, i don't know what am I doing wrong but I feel like my overall understanding and strategic thinking is degrading under pressure of time. I'm making a lot of inaccuracies and blunder that I would possibly never make when I am awake. i don't know what going wrong the performance is shameful and when I analyze the game later I feel so stupid.
