The critics that hit you everyday if you do not integrate in the pattern get to you (if you are not strong and independent enough - which my lovely person is a though thing to do which takes time and tears); and then you start thinking that you're not good in enough (super wrong thing to do!) and you want to change, and so you put a mask on (metaphorically speaking) and you try to be like them*. And usually they are the persons that are inspired by the superficial TV stars, so basically that's how you get the impression that you have to prove everyone who you are by the brand of your clothing and the high class restaurant you apparently have to go to.
