At university, drunk and anxious (7)
I believe the answer is:
uptight
'anxious' is the definition.
(I've seen this before)
'at university drunk' is the wordplay.
'at university' becomes 'up'.
'drunk' becomes 'tight' (I've seen this in other clues).
'up'+'tight'='UPTIGHT'
'and' acts as a link.
(Other definitions for uptight that I've seen before include "Unable to relax" , "Tense, nervous, repressed" , "Irritated" , "Neurotic" , "Tip thug, being nervous and tense" .)
