I figured out I had BP2 before I went in to be diagnosed so I don't have an anniversary in the same way you do. I can related in the sense of remembering the day my son told me he had cancer--I hate that day!!

Your illness must have been causing problems in your life or you wouldn't have been seeking a diagnosis so try to realize that knowing what's going on is half the battle. Give yourself a chance to grieve, and hopefully tomorrow will be another good day.
