Then I'll ease your mind by disagreeing with you. Sometimes you want to say the character is nervous about his job, but not exactly nervous, he's more like... afraid, agitated, annoyed, apprehensive, basket case, bothered, concerned, distressed, disturbed, edgy, excitable, fidgety, fitful, flustered, fussy, hesitant, high-strung, hysterical, irritable, jittery, jumpy, nervy, neurotic, on edge, overwrought, querulous, restive, ruffled, sensitive, shaky, shrinking, shy, skittish, snappish, solicitous, spooked, taut, tense, timid, timorous, troubled, twitchy, uneasy, unrestful, unstrung, upset, uptight, volatile, weak, wired, worried? If you are finicky about finding the best word that describe your ideas, a thesaurus helps.
