after reading again your first post I recomend stay away of chess for a while... your brain is not working anymore to increase... you are in burnout state for chess..
go out, meet a girl, drink a beer.. play or watch football.. but stay away from chess
stay away from chess on a period. I didnt intended to say to QUIT chess
You should quit
... I fell back down to 1600, in just one night, with 6 losses in a row.
...
I am going to lose my mind right now because usually no great chess player loses like this.
I once lost 20 games in a row. I've also dropped more than 200 points on many occasions.
It happens. You fall down. You dust yourself off. You learn from it and you march on.
Now that you are back above 1800 rating, it's safe to offer you some PRACTICAL advice, coming from a player whose first rated over-the-board chess tournament was back in 1971.
IGNORE your rating.
If you can't do that, then at least de-couple your rating from your ego and from your feeling of self-worth.
For your development as a chess player (to say nothing of your development as a person!) it is essential to prevent your rating and your ego from getting tangled up together. That will only cause damage to BOTH of them.
Try using a rubber band.
... I once lost 7 - 10 games in a row, getting my rating from 1000 to 880. My second tilt period is right now, having lost from peak 1090 to 1040. I am not sad, and why should I be? Chess is all about winning and losing, not taking it into your burden. BTW, I'm 11, and I want to be a chess master in college, but chill, it happens. The good news? LONG - TERM IMPROVEMENT!!! How did I get back in track and gain 200 rating from 880 to direct 1090? I left chess for a few days, did puzzles, lessons and analyzed games instead. I'm finally back after 10 days, and see how much good I'm now. But I just have one question - When I get to the 90's, like 990, 1090 etc, and I get excited about winning just one game to cross other limits, why does the rating fall start from there? I initially use Focus Mode in my games though, so I don't see each other's rating after the game concludes.
I bet your rating play by himself...
if you see 2-3 games lost in a raw, instead of pushing with nerve... go to bed.. sleep, drink cofee.. analyse whats wrong.. drink a coffee..and then go back to play chess
