Hi, Sweety,
it sounds to me like you are in a shock and that's why you have that too calm feeling. Also it sounds to me that you did not ask any questions - goes with being in shock. The doctors unfortunately do not volunteer much information, you have to ask them questions: "what does that mean?" and when they explain, ask them to explain the explanation. If you don't ask, they think you have read their mind and know everything. I know this from experience, and you probably do too.
My prayers are with you
Leena
