Thanks a lot, excellent read, I believe in my case I fear something far worse than losing:

This, lost an insane amount of money in few days with btc, but it felt nothing, now if a reg outplays me and I get stacked I get really mad, even more if I'm overcalling/overbluffing

Maybe it's a good idea to start playing a competitive game that I play very poorly to learn how to deal with this feeling?

Time to play league of legends-- the ultimate tilting game.

I've played only one game of lol in my life, didn't like it. I've used to play dota 2, have around 2.5k hours of that on steam and more 2.5k of dota 1 in my life lol. Very tilting indeed haha.

Will start playing a new format in magic the gathering: modern. I'm pretty bad at it (despite being a competent player in the game on other formats), my friends got some tier decks I can play, but will develop my own rogue deck and try to win with my strats.

I've tried this format a bit and got completely schooled and because of that I felt bad and never bothered to play again. So came back to my usual format (commander) that is 4fun so I could blame variance or people joining forces to kill me early. Always had something to blame other than my bad plays.

Will play this once a week and will play some big tournaments when they happen, maybe will travel to Brasilia to play some. Let's see if it will help me to accept my losses better on poker.

yeah that part too. I just got a 120$ mousepad. I was playing my game like a ***** maniac. 4 days later it has slow spots and im back to my normal self. I can't even bring myself to play, i am just so stressed and angry at my performance even though i am one of the best.

Some of us are weaker than others mentally for some things and theres rarely anything you can do about it besides being perfect.
