Acrostic.

Inevitable, immeasurable, improbable pain.
Melancholic, murdered and severed heart.
Itching, introverted, incalculable nights.
Suffering felt, sorries never told.
Sordid yet solemn, solemn but scarred.
Yielded to too much pain, yet still alive. So alive.
Out to conquer the pain, over everything soon.
Under all this torment, ultimate joy will soon be felt.
