Obsessed

Imagine someone out there....someone who dresses like you, looks like you, even acts like you....
They have a house just like yours, a job just like yours, a wardrobe just like yours....
They watch you.
They're that person that sits behind you on the bus, the person walking outside your house that you make eye contact with for a second through your bedroom window, that person that 'accidentally' bumped into you walking down the street...
They're everywhere and they have one purpose and one purpose only.
To be you.
They want your life.
They want you out of the way so that they can live your life and have it for their self.
There is only one word that describes this person...obsessed.
