Its been my experience that the days leading up to an anniversary are harder than the actual day. I suppose its the anticipation of it. Im very very sorry for your loss. I hope that day passes peacefully for you.
I will pray for you. Our son died 3 months ago; I have no idea how to even be where you are now. My heart aches for you and your family. All we can do is pray hard for each other that God brings peace to wrap us in and for you especially at this time.
