Without money in Tehran, terribly distressed (11)
I believe the answer is:
heartbroken
'distressed' is the definition.
(thesaurus)
'without money in tehran terribly' is the wordplay.
'without money' becomes 'broke'.
'in' means one lot of letters goes inside another.
'terribly' is an anagram indicator.
'tehran' anagrammed gives 'heartn'.
'broke' inserted into 'heartn' is 'HEARTBROKEN'.
(Other definitions for heartbroken that I've seen before include "Suffering from intense grief" , "in anguish" , "sad?" , "Grief-stricken" , "Extremely distressed" .)
