I will never feel unfaithful

I will never feel unfaithful
I will never step aside,
I will never feel unhelpful
Bounded by own mind. 

I will never feel depression
Capturing my only life.
I will never give confession
To a dead or an alive.

I will never pour down tears.
I will never express angst. 
I will never show my fears,
I will never tell my past.

I will never let emotions
Complicate performing jobs
And except unwanted motions,
Words and looks what can be worse?
