Anxious, I'm one receiving medical care (9)

I believe the answer is:

impatient

'anxious' is the definition.
(thesaurus)

'i'm one receiving medical care' is the wordplay.
'one receiving medical care' becomes 'patient' (a doctor's patient).
'im'+'patient'='IMPATIENT'

(Other definitions for impatient that I've seen before include "Fidgety" , "dying" , "those who hate waiting" , "Agitated" , "Job wasn't" .)

I've seen this clue in The Sun, The Times and The Telegraph.
