I just read this, how is your sister in law doing?

 

I had a friend that killed himself 3 years ago last November, his wife found him and she still cannot get the image out of her head.  He left behind a son (then 2 years old) and his wife and there was no apparent reason for his suicide and she is still at a loss to know why or what might have happened that day to make him do it... he was watching a DVD (he didn't go to work) then he paused it, got up and hung himself.

 

She found it really hard to deal with, and said that the best thing she did was to go to a grief counsellor - someone whom she felt free to say anything too, because they didn't know him, or her or the situation - so when she needed to blame him, she could without fear of judgement. 

She admitted that if she didn't have a son (ie a reason to live) she couldn't have carried on.

3 years later, she is able to be enjoy life without feeling guilty, and has been able to go on a couple of dates - but she felt guilty telling us because she felt that we would be loyal to her dead husband.  We have since convinced her that while we loved him, we love her too and we want her to be happy - so we are glad that she is able to find joy in life again.
