Taking my anger out on other people: The truth on why it happens

I've noticed that whenever I'm stressed or frustrated, I tend to let out all those frustrations on other people. I've gotten so used to keeping every last struggle and personal problem inside of me that I write poetry about it, and even then, I can't recall most of it since it's rooted so deep inside of my brain it would take immense strength to pull it back out. I always wondered why whenever I got upset I would resort to getting frustrated at somebody else, it's like a chain reaction, or rather dominoes. If someone yells at me, then I'll yell at somebody else, and they'll most likely do the same until we all fall down, or in this case, we struggle greatly. Our brains are so messed up we perceive everything and everybody as a fuel for our anger regardless of who they are or what they may be doing. I feel like we’re so quick to jump to conclusions because we’re constantly expecting the people around us to be assholes. And, with trauma involved, our brains make things so much more intense and complicated than they actually are. We don’t realize that we’re just hurting each other over and over again without any resolution to the initial conflicts. It’s a horrible cycle to be stuck in. Though it's definitely easier to shut everything out than to acknowledge those negative feelings, but eventually, it all builds up so much that you don't know what to do with it all. It starts to consume you, and you begin to lose touch with reality in order to cope with the pain. I wish we could all just let it out without the fear of how others will perceive it. For me, poetry is how I cope. The idea of having to show weakness and share those deep-rooted thoughts/feelings is so incredibly difficult and the mere thought of having to deal with that is terrifying. I can never find the right words to express how I feel, but the words I can never seem to find are always there — in my poetry. 𓂃۶ৎ
