I have what I call "bad fighting game days" ...yes a very complicated well thought out name I know, thank you. Whether it is a big losing streak, or just some rage when I'm losing to stuff I know I should be winning to. I never rage quit though, although I did turn off my PS4 once during a set with my friend out of frustration, I was drunk. Sometimes in street fighter I'll just give up half way through a match and just let them finish me for free, which is stupid and I really shouldn't do. The point of this is that you just have bad days sometimes. Take a break from whatever style you're playing. Mess with a new character, then the pressure will be off you to win, because you're new to the character, so you should be losing! And with that losing you will learn. If you're having a really bad day though, I recommend putting another game in for the day. Shoot some zombies, play some Mario, ANYTHING but fighting games. Losing is part of the game, you'll need to learn this and how to deal with it eventually.
