Suffering this year in agitation (8)
I believe the answer is:
hysteria
'agitation' is the definition.
(both can mean a state of distress)
'suffering this year' is the wordplay.
'suffering' indicates an anagram.
'this'+'year'='thisyear'
'thisyear' with letters rearranged gives 'HYSTERIA'.
'in' is the link.
(Other definitions for hysteria that I've seen before include "Emotional and uncontrollable outburst" , "neurotic disorder" , "State of violent mental agitation" , "Uncontrolled emotion" , "display of wild emotion" .)
