I am afraid,
But who isn't?
I am strong,
When they say I shouldn't.
I am pain,
In joyful situations.
I am tired,
During normal recreations.
I am lost,
Without my navigation.

I am fearless,
But no-one believes it
I am meek,
When strength is needed.
I am happy,
During ones bereavement.
I am alert,
With shadows creep'n.
I am found,
But who really believes me.

Who am I?
