Sues insane doctor for anxiety (10)

I believe the answer is:

uneasiness

'for anxiety' is the definition.
(uneasiness is a kind of anxiety)

'sues insane doctor' is the wordplay.
'doctor' is an anagram indicator.
'sues'+'insane'='suesinsane'
'suesinsane' anagrammed gives 'UNEASINESS'.

(Another definition for uneasiness that I've seen is " Apprehension".)

I've seen this clue in the Sydney Morning Herald.
