Father Passed away

Well not sure how this thing works, but any how just found out today that my father passed away. How am I doing? I say good, others say I am being stupid. I guess because I haven't shown any signs of emotional feelings or felt like crying, while I was at work. They asked for me to go home, but I wanted to stay and take care of customers. The only thing that was on my mind was that I had errands to run, cleaning house, sorting out laundry, my rent is due, and assignments to be finish for class. I was more concern about those things than worrying about my father passing away. I guess what I'm saying is people cope differently, I think?
