Visiting loo, daughter is upset (14)

Ross

I believe the answer is:

inconvenienced

'is upset' is the definition.
(inconvenienced can mean upset or troubled)

'visiting loo daughter' is the wordplay.
'visiting' becomes 'in'.
'loo' becomes 'convenience'.
'daughter' becomes 'd' (genealogical abbreviation).
'in'+'convenience'+'d'='INCONVENIENCED'

(Another definition for inconvenienced that I've seen is " Caused trouble to".)

I've seen this clue in The Times.
