Edgy, I have to follow the others (7)
I believe the answer is:
restive
'edgy' is the definition.
(synonyms)
'i have to follow the others' is the wordplay.
'i have' becomes 'I've' (contraction of 'I have').
'to follow' means one lot of letters go next to another (some letters go after or follow others).
'the others' becomes 'rest' (eg the rest of a group).
'ive' put after 'rest' is 'RESTIVE'.
(Other definitions for restive that I've seen before include "Impatient - jumpy" , "Unsettled" , "Unable to stay still" , "Uneasy, nervous" , "Fidgety, uneasy" .)
