That time i gave myself a nosebleed trying to beat prototype 1

So it was the second to last boss fight of the game, I stayed up all night dying and trying over again and again to beat her. On top of that we had to go somewhere that day, so my mom was rushing me to get in the shower. Then suddenly out of nowhere blood just gushes out of my nose. Btw if any medical experts comment on this tell me what it means.
