Daddy there is high and dry (10)
I believe the answer is:
dehydrated
'dry' is the definition.
('dehydrated' can be similar in meaning to 'dry')
'daddy there is high' is the wordplay.
'is high' indicates an anagram (can mean drunk or on drugs and hence disordered).
'daddy'+'there'='daddythere'
'daddythere' is an anagram of 'DEHYDRATED'.
'and' acts as a link.
(Other definitions for dehydrated that I've seen before include "Dried out" , "like the Ancient Mariner?" , "Short of water" , "Drained" , "thoroughly dry ..." .)
