This is not a new problem. He is reacting to thoughts coming up deep within him and this is triggering fear, and it is like a reminder that he has been pestered and so he is being proactive in sounding a warning to tell them to leave him alone. So this is the workings of his own mind and will take time to fade with additional healing work going on from behind the scenes. So you need not be overly concerned about this. It is simply the stage where he is still on a rocky path and will have some emotional ups and downs as he works things through and strengthens within.
