Answer:
I am always in front of you, but yet I am never here. What am I?
I only exist when you are here. Where you never were I can never be.
I fly yet I have no wings. I cry yet I have no eyes. Darkness follows me. Lower light I never see.
If you lose me, you may cause people around you to lose me too. What am I?
I make you weak at the worst of all times. I keep you safe I keep you fine. I make your hands sweat and your heart grow cold. I visit the weak but seldom the bold.
