Matching the Noun
Since this is an adjective, the ending must change to match what you are describing: 'enloquecido' (man), 'enloquecida' (woman), 'enloquecidos' (men/mixed group), or 'enloquecidas' (women).
Use with 'Estar'
When describing someone's current state of being frantic or wild, use the verb 'estar' (to be) rather than 'ser'.
Confusing with 'Loco'
