It's as if insecurity (E)
is a constant
A physical constant
that stays put
and is always the same value
such as those in physics
and mathematics and so on.

A constant like those of the greats
Planck's (h)
Rydberg's (R)
Boltzmann's (k)

Insecurity is a constant for me
And I have named you thusly so
Insecurity - (E)
With a constant value
That remains

In every equation.

If one adds security,
hurt will follow.
If you think someone or something is going to stay,
this fails and the constant of the equation will prevail.

You cannot alter this constant
You can't try subdue it

It is what is

It's basic mathematics
