I don’t know how to best describe it, but I’ll try my best. Since the beginning of the year, I went through some major stress that I won’t be saying what it is, but since that night of it happening, my brain feels completely different. That morning, the back part of my brain felt fuzzy, almost like it was fried. my reactions felt to some situations were also a bit unusual and The next couple of weeks, my brain felt like it was dripping water and felt dry on some occasions. my eyes even started to feel weird when moving them along with a strange pressure and started moving down the back of my spine. another couple of weeks pass and it seemingly went away, but I felt considerably more tired, came back again another couple of weeks, now going completely down my spine, to my butt, and/or to my left leg(which feels cold, but never to the point of shivering nor could feel the cold sensations when I placed my hands near the cold area.) The entire time, it felt like some parts of my brain were not functioning properly. Not sure if it’s also related to it, but it feels like visual perception and auditory perception keeps changing for no reason.

TL;DR: Something majorly stressful caused my brain to feel weird and have strange sensations.
