Any suggestions, please?
I can’t improve my chess game, and my chess skill is decreasing. :(
Take a week off, go do something completely different; then try playing again.
Breaks are important.
I note that someone at your level should already know about tilt, and days of rest.

You should play blitz and bullet less because blitz and bullet make you play crazy (you sacrifice the quality of your playing to save more time with hope that your opponent's time will be over). As Michail Botvinnik said: "Blitz kills the soul of chess", so I think you should play rapid or classic game. The second advice: solve 50+ puzzles everyday (you can use Lichess to solve puzzles, it's completely free). The third advice: play until checkmate (I mean you shouldn't resign even if you have the worst position because nobody is perfect: your opponent can make mistakes, and you can make a stalemate trick if you can't win). It helps you to analyse your mistakes in the games (I always play until checkmate and it increases my braveness). Whatever, you need to have a rest from chess (you must be tired to play a lot)

It is most likely the interaction between experience and concentration.
Imagine the 1st time you hit 2200. You were probably very excited to be breaking new ground, and thus giving it your full concentration. But that was unsustainable because of insufficient experience, and so you settle in a range of like 2150-2250. Although you are constantly gaining experience, 2200 soon feels "old" and you start to not give each game nearly as much effort as when you first hit 2200. Eventually, when your experience becomes high enough that you can beat the people in that range without concentrating fully, and as soon as you begin breaking new ground again, you will start concentrating as well because of the novelty of a new high rating, producing a rating spike. Right now I think 2243 does not feel like a milestone, so experience and concentration are working in opposite directions at the moment.
(just a personal take, sorry for the long answer, but I have told this to people before and they I think it is a common occurence)

The biggest reason people struggle in lower-level chess is because of blunders. They make them in almost every game.
A mistake can instantly put you in a bad position, no matter how well you played earlier: if you had great opening knowledge, great positional skills, great endgame skills, whatever; a single mistake can change everything (you lose a piece or get checkmated).
So, how do you avoid blunders? Follow this simple algorithm:
While avoiding blunders is crucial, I also share a few basic principles with my students. These principles help them figure out what to do in each part of the game - the opening, the middlegame, and the endgame. Understanding these simple principles is like having a map for your moves. I provide my students with more advanced algorithms that incorporate these fundamental principles. When you use this knowledge along with being careful about blunders, you're not just getting better at defending. You're also learning a well-rounded approach to chess. Keep in mind, chess is not just about not making mistakes; it's about making smart and planned moves to outsmart your opponent.

Thanks 😊

Sometimes it's bad luck. Just stick with it. Don't look at the past 1 week, 2 weeks, etc. Look over 1 year.
Life is like that also. Sometimes you have black lane, sometimes you have white lane.
Yes, while I was reading your comment….me:

Anyone who reaches 2300 has no right to complain. Get a good coach.
I think after 2300 you can start making money by doing quality streaming of your play :-)
Anyway, thanks for your suggestion.

Help me please, I can’t improve my chess game, and my chess skill is decreasing. :(
first of all try to improve opening
Yes, 👍, thanks.
PS: 😂😂, the most incredible thing is that in those all games we have played, I played the opening badly XD.

Have you do ever a stream?

XD, I pronounce English like a 2 year-old child (yes, I can write English, but my pronunciation is so so, so bad). Also, I did stream, but I had 0 viewers, I played chess, I am also good at Puzzle Rush, I did 2 or three streams of that, and I also had 0 viewers, so, bruh, make money by stream is a dream
No tienes que hablar inglés si no te sientes confortable, algunos americanos hablan español también (and korean im kinda a language guy lmao)

umm, it is hard for players of your level to increase
I think 2300 rapid is already amazing...........
( I increased my rating from 0 to 800 in 3 months, but it may take me 1 year to increase it from 800 to 1000)
same with you, I guess

Help me please, I can’t improve my chess game, and my chess skill is decreasing. :(
Getting advice from people who play chess is a waste of time. They will give you a 1001 different reasons why you can't improve. Just don't care about improving, you'll never be a GM or IM anyway most likely. I think chess was designed for narcissists, if you take chess too seriously you might end up becoming one.
