Why do I feel that this poem resonates so deeply with everything I feel?

Frozen
by Natasha Head

I have seen a life laid to waste,
in the name of pure stubbornness,
in the absolute definition of denial.

I see my own life.
Caught up on the same rails,
charging full steam ahead,
to a tunnel where no light shines.

The gates of experience fly by.
Still frames of adventures
I have excused myself from
for reasons, for selfishness.

Vanity . . . shame.
The double yellow line,
solid and illuminated,
laughs as I attempt to find the nerve.

To dare cross.

Throwing up walls of resistance
as the hourglass bleeds
grains of sand I can’t afford.

I have seen a lifetime
laid to waste,
and in its shadow,
I have seen my own.
