Why do I always get so mad I want to bang the table when I lose in bullet?

Yeah happens to me to. 

I don't get that mad, but that's just me. At least by being mad, it shows you care a lot about the game.

Because you care too much about your rating and winning / losing instead of concentrating on your strategy and learning from your mistakes. 

Idk for you but yesterday I went down 110 blitz rating points. For me it’s less of “I have a bad rating” and more like “why am I losing to these low rated idiots”

which leads to “I am an idiot”

Very sad. So I went outside to run for a little bit.

No, i dont think so,but you are.

This is one of the reasons why I always play one game at a time. I get easily frustrated when I lose. Also because I like to analyze matches after they're played - so the 'Y U NO accept rematch' banter is bs.

Anyways, bullet may be too high-paced for your liking when emotions like rage enter your game. I see you're over 2000 rating so it probably doesn't count for you, but the rage part is still annoying to you I can understand.

Suggest you might do as I do---I never lose at bullet.

when ı lose ı get sad really much

I'm a 1400 in rapid. If I lose to a, for instance, 10 1100 rapid people, and drop 200 rating pts, that'd be what I'd be thinking.

I don't know, its like dying in Minecraft or in fortnite.

agreed, you put your whole self into the game!

If you have ever won with 0.1 seconds left you'll do the exact opposite. Given enough time you'll just see it all as relative, wins and losses.

One rule I follow strictly is no rematches among people I don't know. It turns the game into an ego battle and may send you into a downward spiral pretty quickly. Also, to avoid undetected cheaters or sandbaggers gnawing at my rating.

Because it is an human nature. You want smooth journey. And only some have luxurious to have them. 

Like ElMisti said, you have the wrong objectives while playing. You should be, in a strange way, actually happy to lose. Losing means you made a mistake, recognizing the mistake will lead you to avoid it and thus, over a period of time, become better. You don't learn if you keep winning games.

If you get mad, you probably don't enjoy the game for its core values, you enjoy the game because it lets you win. Winning feels good. Maybe you tie your sense of self-worth to your Chess rating. So if the rating drops, your own, personal value drops (in your mind). Hence the defeat is suddenly a personal attack and you get, understandably, emotionally invested and mad.

Try approaching it like this: My opponent probably knows something about the game that I don't know. He/she will use that knowledge to beat me, but I can learn from it and next time I'll be prepared. The other person is just a regular player like you, probably living a similar life. It's not some "evil internet guy/gal" who wants to bully you. He/she probably just spent more time playing Chess and is stronger than you. It's not personal, it's purely skill-based. 

Take out the emotional edge by assuming you're playing a friend in a real game. Try congratulating your opponents sometimes for great moves. It will change your mindset (for the moment) almost instantly and clear your head. Try to not look at your rating. Your goal should be to improve your skill (or just play for fun). If you do that, your rating will increase automatically. No player has ever achieved greatness without acknowledging their opponent's great skill.

lol

Once I dropped 160 blitz rating in one day and I literally wanted to quit chess haha
