Rip your top, being emotional (5)
I believe the answer is:
teary
'emotional' is the definition.
(likely to burst into tears)
'rip your top' is the wordplay.
'rip' becomes 'tear' (synonyms).
'top' indicates taking the first letters (in a down clue, the first letter is top).
The initial letter of 'your' is 'y'.
'tear'+'y'='TEARY'
'being' acts as a link.
(Other definitions for teary that I've seen before include "Lachrymose" , "Weeping" , "Emotional" , "Upset" , "Weepy" .)
