If you're obstructive, I'm deep in distress (6)

I believe the answer is:

impede

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

'if you're obstructive' is the definition.
I can't judge whether this definition defines the answer.

'i'm deep in distress' is the wordplay.
'in distress' indicates an anagram.
'deep' anagrammed gives 'pede'.
'im'+'pede'='IMPEDE'

Can you help me to learn more?

(Other definitions for impede that I've seen before include "Hold back" , "Obstruct or thwart" , "Hinder or hold up" , "Cramp" , "Handicap" .)

I've seen this clue in the Evening Standard.
