It's simple @sayee, people has been and always be jealous of things that they can't do and hence they will start badmouthing and trolling..

this girl shows the courage to stand up and fight the situation.. and that many can't do

The girl has already proven how strong she is its the rest of the world to grow up and get on with their lives.. she is already on her path of success its the rest of the world that needs to move forward..

I heard someone say this. "If you heard trolls spreading rumours against you and if you have enemies, it's a sign that you stood for something in your life"

My best wishes to the brave girl.. and dear troll you are also doing a pretty good job at wasting your lives...
