Same, my solution is to lose every game (and try not to be banned for sandbagging) and then crush some noobs and you will feel great - that mindset shall separate you from the casual 1600 rated players because you have adapted a killer mindset - beat these scrubs. If you attempted the above and it didn’t work. YOU NEED TO TAKE A BREAK! Don’t look or interact with a chessboard or play a game for at least 2 days and you will come back feeling refreshed and ready to improve.

Don't take a break. Like physical fitness, if you take a break your ability will decline. Just do puzzles or play the computer if you're not in the right frame of mind.
