Feeling Angry

I used to get very angry before, like for and with everything
Like back when i was younger i used to hit my computer when something went wrong, and in the era of windows 98 and stuff, it used to go bad all the time.
anyways, yeah, getting angry sucks, because if fucks up the mood and the mood of the people around you.. but what if you get angry at the people around you? or get angry at something around you?
i discovered that i get nothing by getting angry but at the same time it's something i guess i need to process the situation of why i got angry at the first time.
it was something that happened? it was someone?
i'm writing this because i feel kinda angry, because i feel my feelings and wishes kinda invalidated, maybe kinda brushed, not even invalidated so i don't really expect this to make too much sense other than just chill a bit writing.
at least i learned and worked tools so i don't reallty get angry destructively... like it used to be... so i'm doing great progress.
