Keep Afloat and Write "Deadlier"

Quiet
Not that I choose
To keep
Lips sewn shut
I just don't
know what to say
Don't have the words
To say
Too many words to say
One question
What do I say
In return to
What you are saying
In shock
Tongue locked tighter
And so much tighter behind teeth
I come off as careless
I wish I could care less
But you see I can't
Silence is deadly
But don't be deceived
By what is shown outwardly
Though my face is emotionless as stone
Inwardly I'm searching
Inwardly I'm digging deep
Inwardly I'm solving
This equation of words
One question
What do I say
What do I say
When words are so deep
And all I have to offer are shallow
Responses
What do I say when messages
Are deeper
Deeper than
What I see on the surface
What do I say to the person
Who is inwardly doing the same
Inwardly searching
Inwardly digging deep
Inwardly solving equations of words
Inwardly just the same
Screaming for
The other party
To receive the message
Silence is deadly
But saying the wrong
Words and the wrong
Time is deadlier
