you're only afraid when you know nothing 'bout it

One will only be afraid when you have no idea on what is it, or what is going to happen next.
If you had known, what is there to be afraid of?
If you had known, you would have faced it like any normal stuff you usually do.
If you had known, there will be no surprise that'll jump out of the sudden.

That's the root cause of being afraid.
So, do not be afraid.
Face it, if not learn 'bout it in order to face it.
You can do it.
There's nothing to be afraid of.
