Knowing everyone is an individual person scares me.

I'm not sure if it's the vast amount of people on the planet or just how we are all in this together. Something scares me when I think about people individually like people with disabilitys (losing an arm or leg) they just gotta go on like that because what can you do. Not even that but the fact that death happens everywhere also. One moment you're walking down the street then next moment your lights are out (scenario "caught by a stray bullet") shit like that. One moment there is a fully operational brain like mine then the next I'm telling at a dead body to get out of the street. Something about the way my head looks at this world scares me like really scares me. Individually we all are just trying to get through life you know. Just trying to make the best of what's here. Next moment my mind falls into this "imagine all aspects of this situation" mind set where I literally imagine all aspects of it and kinda get carried away too. Man just won the lottery (what if someone mugs him for it) (what if his wife divorces him for it and takes his money) (what if he's old then we can just wait till he croaks) (what if he makes it home but just has nobody to spend it on) (what if he overdoses using the money) Idek why my mind does this. It really helps when I'm doing critical thinking but other than that I just scare myself.
