My wonderful, strong Papa passed away early this morning

I am heartbroken. I feel like I can't think. My Papa is a strong Marine. In his last days, he was on hospice care in his home with my mom taking care of his every need. She was helped by my two uncles. It has been so hard not to be there to take care of him like I did for my perfect Grammie, but since we are hoping to adopt a baby that is due any time now, I could not risk leaving. That was a excruciating decision to have to make, but a few days ago my Papa told my mom he did not want me to come out there. He wanted me to be here in case the baby came. I know that I was able to take care of my Grammie by helping her poor body but that would have been humiliating to my Papa for me to see him like that. I would call my Papa almost every night since my Grammie passed and I saved all the messages he left me telling me he loved me. I can't play them right now, but I know I will be glad to have them later. The last time I was able to talk to him was three days ago. When he spoke to me, all that would come out was mumbling but I know he was telling me he loves me. I wish I had said so much more, but I wanted to appear strong for him. I love my Papa so much. I miss my Grammie terribly. How can the worst time of my life also be a time when we are expecting such a miracle? I so badly wished my Papa could have met Baby Girl and held her. I don't know what to do from here. I can't call him ever again. I still need my Papa and Grammie. When I think of him, I am still a little girl he holds high on his shoulders and takes around the yard in a wheel barrel. He used to play baseball with me in the back yard and he would stand right by the wall so I could hit a home run over the wall every time. :) I loved looking at his Marine tattoos and seeing his eyes lite up when he talked about his service in WWII. He was proud of his service medals and his purple heart. Most of all, I love how safe and secure I felt around him. My wonderful husband asked my Papa and Grammie for my hand in marriage and I am so grateful that he was so mindful of the role they played in my life. My mom is going to wait and have a double military ceremony for Papa and Grammie when we go out to California once Baby Girl is here and old enough to travel. I am so glad she is waiting for us. Today I am lost. If you know my mom, please give her a call. She has been taking care of Papa 24/7 and could use the support.
