Oh I see; I had not seen that post! Good! Thank youNo... now you've abandoned what was otherwise a good structure. "It took some time for the trauma to recede" is what you'd want; you can add "me" back in, as Myridon suggests, by saying "...for my trauma to recede."
We still have to deal with the question of whether or not traumas recede. I think that's ok; Myridon does not.
