There's also this, which I realise is talking about the loss of a child before it's first birthday. I don't think there has been a study on the parents of teenagers who die, perhaps there should be, but I suspect it would give similar results.
Bereaved parents die of broken heart

Some of these deaths can be linked to poor health before the loss, but many seem to factor around suicide, a decline in lifestyle due to the stress of grief (such as alcohol or drug abuse) but others are put down to grief and stress suppressing a parents immune system and making them more susceptible to disease.
The risk is highest up to ten years following the loss of a baby but is still present for up to 30 years after the loss. They believe it declines as the initial intense pain of grief subsides.
Again, this study was of parents who lost babies, not teenagers.
But I suspect the effects of grief would be the same no matter how old your child is.
And this man has dragged out the initial grief, he set up the pages and started the abuse so quickly, and dragged it out so much for these families.
His mental and physical health should be taken into account but so should theirs. It is no less important. The damage he has caused to them could take years to show itself. If he has to be punished as well as rehabilitated, in order that those families can try and heal from the pain he has caused, then so be it.
I don't know if the other people who commented on the sick pages and videos he set up have been punished, but they should be and I hope they are.
I don't know if the bullies who drove Natasha to her death have been punished, but again, they should be and I hope they are.
But even if they haven't been punished yet, it doesn't mean that he shouldn't be punished.
But the families of his victims have been punished, and will be for the rest of their lives. It would have been a slap in the face to them if he were allowed to walk free, even with a course or some form of counselling or treatment or education programme.
It's still a slap in the face that the others responsible for the nasty comments may still be free. That can only be rectified if they too are caught and serve prison sentences alongside of Sean Duffy, not instead of him.
