What happened that made you from “too nice” to “don’t give a fuck” person?

Back in my senior year of high school I was in a band and everything seemed fine. I had a friend who showed every sign of being a psychopath. After I joined the band he claimed I stopped hanging out with him but in reality I didn’t talk to him for one week because I was working on my band. He then turned around and told my friend group that I was a piece of crap and that I support sa which I don’t because it happened to me when I was young. Then my whole friend group turned against me even after I told them none of it was true. Made me not care and after that I stopped caring what people thought about me because I figured if my best friends wouldn’t listen who else would?
