i'm really sorry to hear this.
From my point of view, this new policy shouldnt affect people like you who have started the process or even have been offered training admissions.
Anyway, the more you look at this disappointment and dwell on it, the darker your hear gets.
Remember old saying "Where the Lord closes the door, somewhere He opens a window" (gotten from the movie: Sounds of Music).
You can never tell what you have been avoided from. So cheer up. Good things lies ahead.
I wish you all the best.
