How do I improve in chess, I´m only crying.

I'm not great either but my tip would be, don't move a piece unless it's protected by another. This may be a "given" but honestly I have blundered so many times by moving a piece and not checking to see if one of my other pieces can take the one that just took mine.

It is difficult to give advice to a player I barely know. However, I've reviewed your most recent rapid game. Let's go over it and see some of the mistakes you might be making.

Your reaction to Ne4 on move 3. You saw the bishop was under fire, and decided to move it. But you failed to question if this was even necessary. It wasn't. Your bishop is being protected by the knight on f3. You might think this is a minor mistake, but its actually pretty bad. For two reasons. Firstly, you played Be3. This prevents your e pawn from moving. Which prevents your light bishop from becoming useful. Basically you've halted your development. Secondly, If your opponent takes they've wasted tempo. They have given you an extra move.
On the very next move you do this again. You kick the knight with c3. Why? Its not doing anything.
That was an interesting turn of events.
On move 9 you played g3. There is nothing wrong with this move at all. I'd just like to point out, you could have played this during the moments I mentioned above.
10. Bh3 So what's the idea here? Take the bishop when the pawn moves? That's just an equal exchange. Instead, I would play Bg2. Looking to gain vision of the long diagonal in the future. Maybe playing e4 sometime later.
13.fxe You played g4 to prevent g4 from your opponent. You could have just done nothing. And if takes you take with bishop.
15. I really hope I don't need to explain what you did wrong here. Chess is a silent conversation. You should always be thinking about what your opponent is doing on every move. I see you have a lot of daily games going. That should help you realize these mistakes more. Make sure to use your time wisely observing your enemy's options. Ask yourself "If they could play another move, what move would they play?
16. Kf1 I have no idea why you did this. Scared of g pawn taking something I guess? Fair I suppose.
21. f4 I don't even... You can just move the knight.
22. Nb5 Where on earth, heaven, hell, and tuna sandwich is this knight going?
24. Nxc7+ Never mind your opponent gives your knight a purpose for being on that square. No idea why. Also, why didn't they defend their rook with the king? Idk but you got super lucky from this double blunder.
Conclusion: You aren't looking at all of your options. You aren't thinking about your opponent's plans. You clearly don't have a plan in the opening. Learn some basic simple openings. This page lists some for you. https://www.chess.com/openings

One more. Here is your most recent bullet game.
https://www.chess.com/analysis/game/live/80082572775?tab=analysis
3.Bd6 Um? Wasn't your threat dxe? That's a free pawn.
6.Nh6 Ok? And what if h3? Now your knight has no where to advance to. And f7 is just so passive with no future. I would have liked my knight on e7 at least. Fighting for control of d5.
7.Ng4 Alright, we need to talk. Is this what you do every game? Cause if so I need you to at least realize the king is defending f2. You need a piece to defend the knight. Its called teamwork. Your pieces must work together. Also you straight up just hung your bishop.
9. Nxe3! I don't know if you calculated that, but its very clever. Your plan is fxe3 Qxe3+ ... Qxd3 yes? I like this. This is fantastic play. Unfortunately, there is 11.Rxe7. That said, this is still the best move. And your opponent fails to notice it. Beautiful.
11. Qf7 NOOOOOOOOOOOOOOOOOOO! I mean you have the right idea but no no no no no no NO! So close to perfection! This loses you the right to castle. You should have instead castled right away. Then move your queen.
14-16 Just b3. Your bishops have two directions they can go
16.Bxf5! Excellent! simple counting exercise. You have two attackers they have one defender.
20.Nd4 New players tend to ignore pawns because they think their too weak to do anything. Thus you played this move. At least that's what I assume happen here.
21.Nxb3 You realized you hung your knight and quickly did something about it due to time. Fine. More than acceptable. What is not acceptable is you once again ignored a move your opponent has played. EVERY SINGLE MOVE you must question what they are doing. This is especially true in bullet.
22.Qxe1 Oh ok. I guess you were in a panic or something.
23-24 You can just play Kf7.
26. Rook hung time scramble obviously
27. THATS MATE! THAT IS MATE IN 1! My boy! My man! My dude! Or lady. That is literally a back rank checkmate! But ok game continues. And you win their pieces. Nice.
43. Its just a ladder checkmate. Qg1 Rf2 Rh2
Conclusion: You are not a good player under pressure. If that is what you enjoy, continue. That is what hobbies are all about. That's what life is all about. However, I have a personal recommendation if you wish to get better quickly. Since you enjoy fast games, and longer games bore you I assume, why not try blitz?

I dont have Premium so I cant analyze anything.
I watch Videos but how is that supposed to help me?
Other players dont help me and I dont have the money to buy a coach.
Watch chess, it actually does a lot, instead of watching boring documentaries, just watch GothamChess!

@chryoyo0
Whoa why did u even do that? Thanks a lot!
1. I´ll read through the things later, when I have time.
2. In Bullet I sometimes blunder, because it makes the enemy have to think more / checks him and he has to invest more time.

The most clearly explained of all the tactical patterns are on "chessfox" site. In simplest way. The most confusing part is double attacks: beside forks, they call 'double attack', also, when two pieces threatening another (opponent's) two hanging pieces "one on one" - all at the same time (insufiently defended piece is also considered "hanging") and not taking such a piece is also considered "blunder" (when you not take hanging piece is also blunder (heavy error!)). 4 elements of chess - time, force, space and pawn structure (according to Seirawan's first book). Let with some very precise AI get all the answers but not chatGPT 3.5, it "hallucinates" but "perplexity" browser is better with daily uses of GPT4 of five times "copilot".

When you have same number of attackers on particular square as the opponent has defenders, you can't attack! You must have at least one more attacker then opponent has defenders for particular square, to win that piece/square. And vice-versa, when for particular square there's the same number of attackers/defenders for you and your opponent, then you could relaxedly think about other places of the board and not loosing even a milisecond about thinking of that square.

Stop playing bullet. In fact, don't even play blitz. Play rapid 10 minute games at the bare minimum. Fast time controls don't give you enough time to check whether a move is good or bad before you make it, or enough time to analyse for threats. You will only improve very slowly (if at all) if you don't consciously learn patterns. That means recognising when you're about to repeat a mistake which worked out badly for you last time, and choosing to try something different instead. With bullet and somewhat blitz, the games go by so fast that you won't absorb the patterns properly to be able to recognise them the next time.
Blitz and bullet are not for learning, they're for sharpening your instincts so that you can more quickly and confidently respond correctly to patterns you've already learned. That way, you'll save more time and brainpower when you do play in slower time controls, since more of your thinking will be automatic without needing to calculate everything, you'll just see a series of possible patterns you already know and be able to choose the one with the outcome you like the best.
But not without learning those patterns in Rapid first.
underrated reply btw
Thanks @nik1111 !
