Everything I am reading here is consistent with the perspective of someone with a difference in ability (probably neurodevelopmental) that has experienced persistent social rejection as a result. People systematically fail to recognize or emphasize with this.
The person I responded to seems like a lost cause, my response was more intended to sway other young people who might be reading along.
Are people like the parent poster not also real humans with real flaws? Do you really understand that yourself?
I know this is a very depressing thought, but you don't have to deal with them someday. Even if there's no other way out, there's always suicide.
