Being stared at, I sobbed loudly (9)
I believe the answer is:
eyeballed
'being stared at' is the definition.
(I've seen this before)
'i sobbed loudly' is the wordplay.
'i' becomes 'eye' (I've seen this in other clues).
'sobbed' becomes 'bawled' (I've seen this in another clue).
'loudly' indicates a 'sounds like' (homophone) clue (when spoken - not silently).
'bawled' is a homophone of 'balled'.
'eye'+'balled'='EYEBALLED'
(Other definitions for eyeballed that I've seen before include "confronted" , "Stared at" , "looked at" , "Watched" .)
