I cry for help and somehow stay in a balanced state (8)
I believe the answer is:
isostasy
'a balanced state' is the definition.
(state of gravitational balance or equilibrium)
'i cry for help and somehow stay' is the wordplay.
'cry for help' becomes 'sos' (an SOS message sent in an emergency).
'and' means one lot of letters go next to another.
'somehow' indicates an anagram.
'stay' is an anagram of 'tasy'.
'i'+'sos'+'tasy'='ISOSTASY'
'in' acts as a link.
(Other definitions for isostasy that I've seen before include "earthly balance" , "Geological equilibrium" .)
