How to deal with losing

Maybe. I'm down to 1150 now and get annihilated even by players rated far below that.
I use to be ranked 500 in standard.
Greatness is a choice.
You can choose to get better.
Or
You can choose to give up.
Either choice you make will be correct.
My personal choice was to get better. I'm no longer ranked 500 in standard.

Wow. I like the Michael Jordan one. It encompasses what I always say about chess. Embrace your losses, each is an opportunity to learn something. You just have to go through each lost game and find why you lost. Every single one. Then, make sure you learn that lesson and don't repeat that particular mistake.

I lose a lot latley, I think it has to do with the rating adjustment thing from a while ago, but anyways, I just start the game knowing I might lose... for example, French deffence and I am black. I know for a fact balck only wins 28.6 % of the time, so... If I lose, its not a huge deal, as long as I understant why I lost, I know I learned somthing. that helps me a lot.

Insult everyone.
Throw things at people.
Behead a kitten or something similar.
Or you can also make an effort and win 100% of your games so you never get angry.

Maybe I'll just quit playing chess then. There's no point continuing and losing every match so badly.
Do what I've done. Quit playing for a while and go on a tactics training binge. I see that you've never done any tactics training on this site, or if you have you've cleared out your history.

wallow in self-pity, or post a troll thread as if you are wallowing in self-pity, basing your estimate of your own worth and intelligence on losing some chess games. you are on the right track.

Greetings everyone. Forget about the illusion that you don`t have enough talent to become a chess master. If you want to become a master follow me on https://twitter.com/BlcScorpion and if you are like me who shares his chess thoughts and chess progress I will follow you.

3. EIGHT WORLDLY CONDITIONS
Vicissitudes of Life
This ill-balanced world is not absolutely rosy. Nor is it totally thorny. The rose is soft, beautiful and fragrant. But the stem on which it grows is full of thorns. What is rosy is rosy; what is thorny is thorny. Because of the rose one will not meddle with the thorns nor will one disparage the rose on account of the thorns.
To an optimist this world is absolutely rosy; to a pessimist this world is absolutely thorny. But to a realist this world is neither absolutely rosy nor absolutely thorny. It abounds with beautiful roses and prickly thorns as well, from a realistic standpoint.
An understanding person will not be infatuated by the beauty of the rose but will view it as it is. Knowing well the nature of the thorns, he will view them as they are and will take the precaution not to be wounded.
Like the pendulum that perpetually turns to the right and left, four desirable and undesirable conditions prevail in this world which everyone, without exception, must perforce face in the course of one's lifetime.
They are gain and loss , fame and defame , praise and blame, happiness and pain.
4. “if you are unwilling to endure your own suffering even for an hour, and continually forestall all possible misfortune, if you regard as deserving of annihilation, any suffering and pain generally as evil, as detestable, and as blots on existence, well, you have then, besides your religion of compassion, yet another religion in your heart (and this is perhaps the mother of the former)-the religion of smug ease. Ah, how little you know of the happiness of man, you comfortable and good-natured ones!for happiness and misfortune are brother and sister, and twins, who grow tall together, or, as with you, remain small together!”
― Friedrich Nietzsche,
5. Self as context teaches the person to view his or her identity as separate from the content of his or her experience.
i think sometimes you can lose alot of games and make silly mistakes if you have things on your mind

When losing a game of chess, one is forced to accept the fact that he is less intelligent and has a lower self-worth than his opponent. How do others deal with the fact that losing in chess (or any competition) is absolutely unacceptable?
Your statement is irrational. This form of extreme overgeneralization can only create a cognitive dissonance. It is not reasonable.

Come on, don't get down on yourself. As I said in reply to another of your posts, you've just picked up some really bad habits that you need to shed. Just take a few weeks off to study and you'll be fine.
