I'm a person who get's real nervous real easy. For example, when I've played a beatmap almost 400 times without a completion, I'm gonna get real nervous when I get close to beating it. Well...I've been about 10 seconds away from beating Just Awake (https://osu.ppy.sh/s/44527) about 4-5 times...and well, my heart just starts beating like crazy and I lose control of my stability and quick-tapping ability and just mess up and fail...I will beat it the day that my heart stops beating...saddening, really
