Bulimic struggling to contain current incidences of depression? (8)

I believe the answer is:

umbilici

'incidences of depression?' is the definition.
(an umbilicus is a depression in some animal shells)

'bulimic struggling to contain current' is the wordplay.
'struggling' is an anagram indicator.
'to contain' indicates putting letters inside.
'current' becomes 'i' (symbol for electric current).
'bulimic' anagrammed gives 'umbilci'.
'umbilci' enclosing 'i' is 'UMBILICI'.

(Another definition for umbilici that I've seen is " Cords can be cut".)

I've seen this clue in The Independent.
