You Are a Zombie
Like a zombie, you can't really help who you are today. You're a product of your past.
You tend to be needy to the point of being borderline dysfunctionally co-dependent. You literally can't exist without other people.
And once you set your sights on someone, you become obsessed with chasing him or her down.
When you want a person, you're not exactly subtle. You are forceful and honest... you have no trouble expressing what you want!
