Am I being Fake?

Hello everyone, today i ask of your opinion on Smthing.. i am 18.. ever since my childhood my father has had anger issues even tho he was nvr violent but he would get angry too soon probably because of the hectic work he would do all day long.. having grown up in such an environment i have always wanted a way out of loud noises, verbal fights and similar things.. to be careful to not become the reason of ruining the family's mood by angrying him by disappointinh him or not living up to the expectations i have always been very calculated and careful with what i speak in front of others.. i hardly speak to anyone intuitively without any pre-planned.. the only times i do it's abt general stuff like games or sports.. No word comes out of my mouth without processing and choosing between the provable results.. even though my father's anger issues have magically disappeared since the Covid outbreak and lockdown but i still carry that "Why tf is everyone so angry always when we can just be happy all our lives not caring abt any other stuff" + "If i say this it will cause this if i say that that should happen.. etc. etc."

It has become a part of my behaviour to nvr make senseless or intuitive decisions (except some very imp ones), nor do i reply to Smthing important and socially significant that could trigger ppl to call me out for anything without consideration.. i told abt this to few friends and they think I am not being myself.. I m trying to be a perfectionist while perfection is unachievable? some have labelled me as fake (not that i care abt now after knowing their true personalities) but if what i do is classified under being fake i.e. to think abt every single possibility to make a decision or even to talk about stuff.. i feel like its that fakeness that has become me and everytime i am being myself ppl believe i am being fake.. And noone can be as right as i portray! while i actually don't portray anything it's just deeply rooted within me to calculate every possible outcome and then choose the one with most peaceful passage..

do i really need 2 chng.. if someone has overcome this hunger for righteousness in the smallest of situations and calculating everything thus vr being surprised... suggest me how..i wud b grateful 2 u
