Tough choice (7)
I believe the answer is:
dilemma
'tough choice' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dilemma that I've seen before include "a problem for Shaw's doctor" , "I lammed away to find perplexing situation" , "The choice between courses of action, all equally undesirable" , "Difficult problem" , "Situation requiring a choice between (equally unpleasant) options" .)
