So I've known that the popular girls @ school tend to party a lot etc. literally all they do is get drunk on the weekends.

It's usually the popular girls who are addicted to alcohol. Drinking their life away. Do they do this because they are so fucked up in the head?

They seem to live nice lives and have the perception of a good girl. But I know it's just a facade.

Can someone explain to me about these girls being so fucked up in the head to where they drink All weekend long?

Why am I asking? My sister was one of these girls a few years back and just got curious.
