She's beautiful. But I think it's the envy and jealousy of her fake "friends" trying to drag her down. I hope she finds some guys in her location to tell her: she is beautiful.
I have always said the #1 "enemy" of long hair girls is other girls with short hair who have jealousy and envy. The jealous girls see the attraction and reaction of men to the long hair ... but they are too lazy or whatever to grow and maintain their own hair...so they try and make the long hair girl conform to the short hair look.
That is why it's good to be a fan of long hair and encourage the girls on the internet.
