Feel shattered and run away (4)
I believe the answer is:
flee
'run away' is the definition.
(to flee is to run away)
'feel shattered' is the wordplay.
'shattered' is an anagram indicator.
'feel' is an anagram of 'FLEE'.
'and' is the link.
(Other definitions for flee that I've seen before include "Maybe escape" , "rush" , "Turn tail" , "Do a runner" , "Run quickly away" .)
