Bereavement and Loss
There are different ways of looking at loss, I see them as five stages, with different intensity of severity in terms of the relationship we have with the person who has died.
When a loved one, friend, pet etc. dies we can feel a sense of hopelessness. It can make us stand back and take stock of our own mortality and the mortality of loved ones that are still alive. When this happens we may have intrusive thoughts and feelings as a result we may have panic attacks and anxiety.
