I "met" a distant cousin through researching the family tree.
We e-mailed about our findings and I was put in touch with two other members of her family, both men of a similar age to her.
Eventually we just became cyber friends, I got to hear about her children and their lives and she about mine.
We never met although she didn't live a great distance away, she always put a face to face meeting off.
One of the other cousins did come to visit with his wife and I am in fairly regular contact with the other.
About 4 years ago I had been in contact over the weekend and she asked me if I believed in life after death, our previous chat had been about cats, gardening, family etc and I was very surprised.
It was our last contact as she took her own life on the Tuesday morning.
Shock can't describe how I felt and this hadn't been the long and close contact you had with your friend.
For several days I expected a message or a letter telling me why. It never came of course.
I hope you get comfort from the memories of your long friendship, I am sure she knows you are with her in spirit.
You will grieve as if you knew her personally.
Best wishes to you and her family during these next days and weeks.
