I don't have any advice, but you and I both had the BD in September, and our W's are WW (although mine's A is over, forced by exposing to OM's W), and I know 100% what you're going through.
I wish you the best, and I'l be following along, hoping for something good to eventually come out of this. They tell us to be patient and it will be a long ride, but you've got other people in the passenger seat riding along with you.
