Hard times for me...

My grandpa Dooley passed away last monday and I ended up going to the funeral in Arkansas. It was a beautiful service except for the part when they opened the casket. I didnt know that they were going to do that. I cant get the image of him out of my mind and I think its making me crazy. Im tired of the nightmares that come with it. I cried through the whole funeral and then some...Im still crying over a week later. How long is it normal for someone to greive? We went to the burial service too and I was NOT ready for that at all! I just want to forget that it ever happened. I think that I have serious PMS along with this ....I cried because I missed Karalee this morning(no i didnt call, I didnt want her to listen to me bawl). I missed my husband terribly and was so happy to be back home with him and my beautiful babies.
I NEVER want to travel with my parents or sister again. And I wont. I wanted to punch my sister in the face....I still want to so I am going to avoid her for awhile, A LONG while.
