What I'm looking for is a noun describing someone confused and awkward as a result of trauma.
The word should replace MAN in the following sentence:
He's no longer the floundering MAN I remember from the day of the accident: his eyes are focussed and determined, his gestures commanding.
This would be similar to the noun "coward" describing someone who lacks courage.
Is there such a word for someone who is confused or insecure?
Also, the one answer offered ("wallflower") perfectly describes someone who is awkward, but not in this context (not related to trauma). I need something more formal, a noun for a person traumatised rather than shy.
