Sorry uk82, I know the news probably came as a bit of a shock even if you expected it. Feeling calm is a normal reaction, one of the stages of grief is shock and gives us time to process things and not become overwhelmed. We tend to cycle through these stages many times.
Sending you good thoughts today, hope you are doing well and finding something to bring joy in your life.
Accept what is, let go of what was, and have faith in what will be
