They don't like you.
Because you're so beautiful while they're not. Insecurity is the word.
So, in order to make them pretty or famous like you. They put some make ups on their faces. Curled their hair. Gossip how ugly you are. Making some stories which is not true and they want more more friends to make you down.
Pity on them.
They don't have originality. They forgot their own. They want your beauty.
So, you need to be yourself and be confident of who you are. Bye
