Dont listen to others

I was always told that when someone is mean to me they like me but I don't think they do I don't show people that what they call me hurts but it really does so I don't listen to them unless we are talking about school stuff if people are rude to me i was told to ignore them and I do when I know people are talking about me I act like it does not bother me but when really deep down I wish they did not talk about me people think that if they keep trying to hurt me it will hurt me and they could find my weak spot but I show them that it does not hurt me but when it really does what I'm saying is don't talk to people who bully you, ignore them, don't listen to them and you will hopefully be kinda happy
