2old, I have said this before I am sure, but I am still asking the same questions as you. Except it is 12 months down the track. While I can acknowledge my behaviours, the sake of everything going from normal to total shock was also a matter of hours. Having the family and friends be just as surprised and shocked, with none of them seeing this coming is icing on the cake. I am still bothered by the same question you ask yourself. What happened? Why? Why did she not even ask to go to MC? All I can do is accept this is now her journey. Do I stay and wait? Who knows.
