Just tell them
The ER Doctor told me, my husband, and my youngest son I had Leukemia right there in the ER room. I asked my husband to call my sister (she is actually a childhood friend, we call each other sister, we’re both only children). My sister is a doctor, so immediately she was in contact with the ER doctor.
That night was phone call heaven, for being an only child, I have many people that care.
The next day, first cousins, second cousins, my children, my mother, friends, and I were waiting for Dr. Engel to give us the explanation and the answer to, what to do now?
