Hi Elaine
I'm asking myself those very questions and it is hard to come up with any answers. But what were you doing before your loss if you don't mind me asking? Working, housewife, mother. If your purpose has been taken from you by your sad loss then finding a new purpose can indeed be difficult. Many people explore their passions, things they have enjoyed in the past. For example, after my mum died I went to college for 8 months to study the English Language one evening a week. Some people in other threads have taken up painting, gardening or walking for exercise and pleasure.
What I have done is made a list of everything I want to do in life, big and small, i have picked one great cause to focus my attention which is very difficult but if you find me in other places you'll see how I'm coping with challenge and my loss.
