Not looking forward to days studying (8)
I believe the answer is:
dreading
'not looking forward' is the definition.
(I've seen this before)
'days studying' is the wordplay.
'days' becomes 'd' (abbreviation for days).
'studying' becomes 'reading' ('read' can be a synonym of 'study').
'd'+'reading'='DREADING'
'to' is the link.
(Other definitions for dreading that I've seen before include "Certainly not looking forward to" , "Feeling apprehensive" , "anxious about" , "Being terribly afraid of something to come" , "Looking ahead with apprehension" .)
