I know the feeling, I tilted 90 points 3 months ago.
I worked with a coach on a plan (chess wise), added mental and physical health as well to turns things around.
It was very recently I got my confidence back and playing well again.
Also talk to friends, family and fellow chess players. It’s important that you enjoy life outside of chess.
I am 1850 puzzle rating, I have played chess every day for 3 years on Lichess and recently moved here. I bought premium, I analyse all of my games, I watch GothamChess, John Bartholomew and more on Youtube, I even bought a couple of chess books. All of this effort has achieved precisely nothing. I began as a 1500 on this website and I have been on a steady losing streak ever since, plummeting all the way down to 1200 has been so depressing for me, I have actually been struggling with my mental health because of chess. How can so many people be better than me, despite all of my hard work? Why am I so incapable of becoming better at a simple board game? I think about chess night and day, obsessed with how I can improve and nothing ever helps. I am so done with this game. It is full of people memorising stupid opening traps and trying to charge you lots of money to improve, there is absolutely no sportsmanship in chess, it is all about narcissists trying to reach the top. My life has taken a serious hit because of this game and it is going to take me a while to recover. I am 33 years old btw so not young or anything, but I have never failed at anything so hard in all my life. I just wondered if anyone else has gone through this - did you see a counsellor, quit the game, or something else? This game has been keeping me awake at night recently and my ego is shattered.
