body's reaction to osu

Getting FC in osu! is hard. Actually, getting any gooder score in osu! is hard.

It's not because of the fact that I'm bad at the game (though, it might be a contributing factor), it's because that when I play and realize I'm getting a good score, I start panicking. Oh shit! I'm getting a better score! [arms get stiff] Don't break! [grips mouse too hard] Don't break! [feels heart start to beat faster] Don-- and then I break. Strangely once I break, my body relaxes. And the stranger thing is, this only happens in osu! (and it's other game modes). In any other rhythm game like MUSECA or Bemuse, I'm fine.

Anyway just thought that was weird. Thanks for reading.
