Terrible news

I was having my lunch when my chachiji called me and asked me if my brother, Nikhil has called me or any other family member has called me. I was enjoying my food and I hung up the phone saying "I will call u later". I call ed after having my lunch, I asked 'whats the matter?' and she gave me the terrible news that my mamaji expired today of heart - attack . I could not speak or talk more, I did not understand what to say or do? I was not in trauma at once but a sudden shock. I hung up the phone and just stood there. My friends came by and waving happily , screaming not knowing what a thunderstorm has just struck the ground. I tried to call my brother because I feel (safe) with him or there is something that says 'I am there for you' . I did not know how to talk to my mother. I was afraid and also feeling guilty in hesitating to call her. I just don't know why I haven't call her yet......I just really don't know.
