Lol, I thought that was hilarious.
Most of the times I turn it off for awhile and come back to it later. Take the time to cool down, and if I'm still just off I stop playing for the rest of the day. I then go back the next day and practice mode it to and then try again, usually works.
Then there was two nights ago where I was off and this guy comes along who wasn't very goood, did nothing but specials and uppercuts and would wait for me to get near in crouch block or running away from me to use his x ray with kung lao and was beating me. I did nothing bit rematch this guy until I was consistentlt beating him. I've never been so frustrated before cuz I knew I could beat him but I dunno just wasn't working or something.
