w8ing is so right. We also go through different stages. I was a big mess when this all started. All I can say is to take it minute by minute, hour by hour, day by day. I too thought the tears would never stop but they did....eventually. I would cry all the time. I would be driving and crying, watching tv and crying, you know what I am trying to say.
I have been through the grief,disbelief, dispair, anger, want to get even, confusion, no sleep, and dropping over 40 pounds. I had to keep going because of my D and S. Someone had to be sane to keep things as normal as possible and that was me because my h had totally lost his frigging mind!!!!!!
Please try and keep yourself busy as possible. Do things for you! Work on you, for you. You will get there.
