Answer:
If you have me, you want to share me. Once you share me, you won't have me. What am I?
I am a type of animal that hang out in the mist
I am filled with garb the price is free. Just return what you don't need.
Before I grow I'm small. When I'm old I grow tall. When I die I give a mighty fall.
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.
