I believe the answer is:

recovering oneself

I'm a little stuck... Click here to teach me more about this clue!

'retrieving personally on regaining one's composure' is the definition.
I know nothing about this answer so I can't tell whether this works.

'regaining one's composure' is the wordplay.
'regaining' becomes 'recovering' ('recover' can be a synonym of 'regain').
'one's composure' becomes 'oneself' (I can't justify this - if you can you should believe this answer much more).
'recovering'+'oneself'='RECOVERING ONESELF'

Can you help me to learn more?

I've seen this clue in the Evening Standard.
