my dad's life is so sad

heya, so first i want to apologise for my bad eglish my grammar is not the best atm ! 

sooooo my dad just broke a fragile container because he was mad, for context mydad is a doctor and he works and study a lot so when came to home he  only wants to eat and sleep, he has a bad temper and he gets mad very easily because he is tired buthe tries to be a good man, my 2 year old sister is very energetic and annoying sometimes, she is cute but sometimes she can be too much for everyone.

my dad was trying to eat after he came bck from work and aparently my sister was being annoying, he was already mad, so he was yealing at my mom so she can grab her and take her back to their room, my mom didn't wanted to hear and she was walking to the room without her and my dad said "i know that you're trying to leave her here" my mom starts to laught and my dad was pissed off, my sister was being x387773448 more annoying and he got very mad, so he just tooke a container, and he smack it in the floor destroing it, i was in my room hearing everything and i run very fast to the living room, my mom was taking my sister to the room, my sister was crying, it was some sort of glass pieces in the floor and my dad was in the couch grabing his head.

my mom told me to clean the mess so i did it and while i was cleaning my dad just stop to watch his tv show and he was just in blank still grabing his head, i saw that he had glass eyes and he wanted to cry because he stoped  to be violent years ago and do this in front of my sis was horrible, so i just clean in silence and after that i give him a hug, he didn't reply, so i just camke back here, to my room and now im writing this.

is sooooo sad, im feeling very bad for him and this whole situation is very awfull.
