my dad died today and I don't want to tell anyone

A few days ago I found out that my dad was secretly battling cancer. The hospital reached out to my older sister as she was listed as his poc should he be unable to make decisions for himself. He was unresponsive so the hospital contacted her. (Our parents divorced years ago) This morning my sister called and told me that he passed away. Our family is all aware, but since I live out of state none of my friends will know unless I tell them. Is it selfish that I don't want to tell anyone just yet? I'm battling my own emotions and don't feel ready to handle all the phone calls and questions. I know it's just love and concern and I appreciate it, I just want to be alone with my boyfriend. Trying not to stress with our growing the bun in the oven. I know he can feel everything mommy feels.
