I cant sleep

I was up all night, I just couldnt fall asleep. I keep thinking about my dad. I miss him so much. But I'm extremely worried about my mother. I know my pain is unbearable, but what about her? She lost her husband, her best friend, her everything. This month they would have been married 46 years. Can you imagine? He lived for her, did everything for her, and now he is gone. She feels so alone. I know she has us kids, but its not the same. She is scared and lonely. She is worried about her future. She is looking to me for guidance, but I dont know what to tell her. I dont have any of the answers.
