A Pair of Ones, a Paradice

A two-faced snake my self-love paralyzed, Whose toxic fangs impurely freeze my will. The one all past events remakes despised, The other future wants will ne'er fulfill; Regret resents my past to make me languish, While doubt my future wrecks and makes unsure. I should prevent my own apparent anguish, Yet doubt/regret combined proves quite the lure. This mix, despair, invents a mess of tricks, My famine's foison in its blest appeal; Defanged and pure, this wretched drug addicts, How like a potion does its poison feel! Addicted to self-loathing's desperate bliss, With blithe despair I tempt this serpent's kiss.
