diabastrous
A state of utter hopelessness and despair that transcends normal adjectives and requires a combination of "diabolical", "bastard" and "horrendous" in order to fairly describe one's mental or physical state; existential dread on a scale that combines fear, self-loathing, physical pain and nausea
