I am someone in hospital, possibly fidgety (9)

I believe the answer is:

impatient

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

'fidgety' is the definition.
(similar in meaning)

'i am someone in hospital' is the wordplay.
'i am' becomes 'I'm' (contraction).
'someone in hospital' becomes 'patient' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'im'+'patient'='IMPATIENT'

'possibly' acts as a link.

Can you help me to learn more?

(Other definitions for impatient that I've seen before include "Restless; intolerant" , "not able to wait" , "fed up with waiting time?" , "Job wasn't" , "Pit at mine (anag.)" .)

I've seen this clue in The Times.
