Spring woe, maybe (6)
I believe the answer is:
asthma
'spring woe maybe' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for asthma that I've seen before include "Respiratory disease" , "Mat has a respiratory disorder" , "Shortage of breath" , "Strange that Mat has difficulty breathing" , "Mat has difficult breathing" .)
