I don't want to lead a life like her's- what do I do?

First of all stop fearing that u will become something u don,t want to.Have faith in yourself.No matter how many traits two people share in this world they are never the same and what makes them different is how they define themselves.Every person is special in his or her own way.No one should justify the way you should be ,its you who needs to decide how you want to live your life and how you want to be remmembered .Every day of your life is a blank page of a book .Its in your hands what you want to write in it.Take care
