I need help trying to be more calm

So, I wouldn't say that I have anger issues but when I get angry, I get very intense. I would be holding grudges and my mood would be sour the whole day...it's aggravating. Not sure if it's a hereditary thing since my parents, especially my dad, have their moments but yeah I think it is an issue I want to resolve for the future. Most things that make me angry are jabs at my insecurities, some of the annoying schticks my siblings do, harsh criticism ("this resume doesn't look like it was made by a sane individual"...really...), and passive aggressiveness at times but I am usually too clueless to really get it as often so not too sure about that one. Any advice would help as I am trying to be more calm and rational with my thinking, thanks!
