Struggles to get hold of bachelor's feelings (5)
I believe the answer is:
vibes
'feelings' is the definition.
(vibe can mean a mood or feeling)
'struggles to get hold of bachelor's' is the wordplay.
'struggles' becomes 'vies' (to vie is to struggle or contend with).
'to get hold of' is an insertion indicator.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'vies' going around 'b' is 'VIBES'.
(Other definitions for vibes that I've seen before include "Mental or emotional resonances" , "Feelings that seem to emanate" , "Feelings emanating from a person or place" , "Emotional stimuli and communicatons" , "Feelings (colloq.)" .)
