I've been told this by some people before but it makes no sense to me. 

I've been a vulnerable person my whole life. Even people I think are my friends treat me like garbage sometimes. My self esteem is hammered, and I don't know how to let go of the years of being "that guy." My horrible childhood and teen years are ruining my ability to pursue a happy life, and therapy has never clicked for me.

I've been having cringe attacks daily for two years over how people have treated me. Even some of the most sensitive and passive people I know are fine with being confrontational with me. My once best friend has said things to me he'd cry over if people said it to him. People with a lot more to live for are fine treating me like dogshit. "Treat others the way you want to be treated" just sounds like woo woo.
