Re: Troubled, Confused, Disturbed - Over these exact words
The -ed suffix is also used to form past participle verb-forms, many of which can also be adjectives functioning as predicative complements in complex-intransitive clauses. Adjectival predicatives ascribe some property to the subject or object ("Ed is nice/fat/clever"; "I consider Ed nice/intelligent/lazy"); those formed of past participles often describe emotions and feelings or other meanings, cf. "Kim is "married/engaged/injured/lost".
