why my vision seems tight and squared?

it's so creepy and i haven't found anyone with the same thing, so i wonder if it's even connected to dpdr. i basically started feeling that my vision is really limited, as i see the flat squared picture. idk maybe im too way used to my wide monitor hahaha but yeah that's scary even though i know that i struggle with derealization. it's just so creepy when you feel worse and find out more stuff that bothers you, idk. anyways, do you guys think it's even connected to dpdr? or maybe someone even feels the same? cuz im tired of thinking about it :_)
