Me not you

I am me
Nobody else
Label me
Box me up
And you will see
You don't have me
For me is not
What you believe
Or what you perceive
Because I am authentic
I am a one off
I am unique
I am individuality
Personified in every breath
From my birth
Until my death
I am me
And you don't get me
For I am spirit
I am free
Beyond the realms
Of you controlling me
Or even oppressing me
I am like air
I am like water
Try to catch me
Try to hold me
But I will slip
Between your fingers
I will not surrender
Me to you
Because I am wise
To all you do.
