I am stupid

So I like this guy but he doesn’t like me back and I still like him even though he doesn’t like me back and every day it hurts seeing him because I know he’ll never like me back and It just kills me inside because the more I see him the more hurt I get and the more hurt I get more sad I am and I’m just tired of being hurt and I know he doesn’t like back because my friend told him I liked him and he completely rejected me and the worst way possible and it just hurts a lot because I really like him and I just wanna cry but I’m so angry all the same time
