Lack of sleep can cause temporary insanity

So I go to bed around 4 am and around 5;30am my roommate decided to play Celine Dion tracks on her laptop and oh did I say it was on about 300% volume and as I nice as I am I ask her to reduce the volume and she does by about 20%Iexcuse my language but What The Fuck?? I then ask if I can give her an earpiece and she declines, OK cool.

I cover my ears with my pillow but still cant sleep,I get up and go to a friends room to have some sleep.Then I come back to my room and shes still as noisy as ever.I am still calm tho, but am getting angry but I'm calm.She starts talking on top of her voice I ask calmly for her to reduce her voice but still NO, so I take a mug and throws it at her head,I am normally a nice person I wouldn't normally do this but I was sleep deprived so I didnt actually regret it.

It hits her head n it cuts deep,I don't really mind and I go  back to bed .I wake up 4 hrs later and she has gone for stitches then I realize how badly I behaved,I apologize and now I really feel BAD but its not my fault i was sleep deprived and I WAS TEMPORARY INSANE.
