Take any exit out in panic (7)
I believe the answer is:
anxiety
This could be a double definition.
'take any exit out' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'panic' is the second definition.
(thesaurus)
'in' is the link.
(Other definitions for anxiety that I've seen before include "State of apprehension" , "Nervousness" , "Disquiet" , "tension" , "Morbid unease" .)
