How to deal with losses?

I planned to only play against better opponents than myself in order to learn from my losses (and it is indeed very exciting to play with people around 2100 on lichess and helps me a lot to improve). But now I experience that losing one game after another can be quite frustrating. Now you need losses to get better, but can you be happy some way losing every game or is it very natural to be frustrated when doing that - no matter how often you tell yourself it's "just a game". Should I keep doing what I do or sometimes play against weaker opponents too?

Do you experience similar frustation when losing due to lack of concentration or time pressure on one single move? I am asking because Ive seen this kind of frustration even among masters on youtube - it seems that even the best get really frustrated about one match (Carlsen) or mistakes in games are stuck in their head forever (Kasparow). Is there a way to learn from your losses but at the same time focus on your strength?

Chess is a little bit contraproductive from a psychological perspective - you need to always look out for mistakes and spend a lot of time on your losses and understand what you are doing wrong if you want to improve. Now how can you even focus on your wins when having to spend so much time on your losses and trying to produce as many as possible by playing against opponents you can't beat? What are your thoughts?

Chess is a beautiful game and I really like it, but I somehow struggle with losing a lot. It's not the same as in other sports like football, because you don't really play for the win, but for fun. You also move your body a lot and get happy alone by doing that. In chess you seem to only get happy by winning a game. Does anyone have an idea on how to be happy no matter if you win or lose and still work your way up to get better? Is this even possible? Is there a way to play for the fun and still play for the win? If you find joy in moving pieces you might not care about winning or losing anymore - but then again you might not care about improvement either. Can you improve without getting frustrated from time to time?

Use the 'quick pairing' feature, let the site match you up with players that are close to your rating level and just play.

Eventually you will stop losing as your rating adjusts downward. When you start winning again, your rating will go up and you will get another opportunity to "learn from your losses".

No.

The only way to deal with losses is to take the game less seriously.
Online chess is not competitive at all.
As you play only better ones consider the score of your perfomance expectation (mathematic) and say yourself, that winning one out of four is an achievement. Learn from the way they play and improve.
I doubt anyone here will be able to give a general advice about dealing with losing. Not an easy topic...

@Funkmaus why do you say online chess is not competitive I don't get that - there are very few to none open chess clubs in my area at the moment, because of the virus - so the only games I can take seriously are the ones online. Also if I have problems online losing, I certainly will have a problem OTB too. I would be okay with winning every 3rd or 4th game, but at the moment I lost 100% and I wonder why it bothers me that much.

Also it is not only about me, I think a lot of people struggle with losing and I thought it might be a good idea to talk about it, because it is the number one reason people quit chess or get angry. Maybe knowing how to deal with losses is the key to success, since you can only improve through them.

@clutchnutz Doesn't work for classical games at rating >2000. There are very few players that play classical games.

Probably not helpful but you could try playing some 15+10 or 20+5rapid games as you get paired with players quite quickly .There’s plenty of time to think about every move as well...
Also losing four games in a row is really not a big deal especially in online Chess, everyone has good/bad days.I find that sometimes the more eager you are to win you are actually more inclined to make blunders and people’s concentration level drops after staring at the screen intensely for a while.Plus you were playing against strong opponents, it’s quite impossible to improve 100/200 points over a few games...

basically just play against people your rating or about 100 rating points higher. set rating restrictions in the lobby to 1800-2100 and play. once you play 30 games and your rating evens out play against people mostly 50-150 rating points above you. it's what I do and I'm improving.

EDIT- typos

Is the problem really just losing or is it watching your rating get lower that you find more upsetting? If it's the latter.. play more casual games until you start winning again.

@Tae7 actually that was very helpful. Since I experienced that my concentration dropped at the third game I guess you are right that staring at the screen is even more exhausting than staring at the board. Thank you for your comment <3

@clutchnutz the problem is losing not the rating points. I don't care about the rating points. I know I am somewhere at 2050 at rapid. But I want to improve at classical games, because I only win in rapid because i am quite good at tactics - I need wins in classical to know my positional play has improved.

@OnlyBetterNoBlitz

Maybe play more games against Stockfish level 5 (~2000) when you can't find a human to play?
