You have had so many positive results from your work that it may be that you have grown comfortable with the situation as there hasn't been much to worry about. Now that things (W) may be distantcing for you, be prepared for the negatives and do your best to detach and let it roll off your back.
I'm not worried about you, since you're one of the most grounded people I know, but when a negative happens to me, it is really hard to keep that bright face on and the PMA up.
