Why on any level, whould it help the grief to keep things a secret? Why turn an illness into something secret? I admire the way the family handled the death of the Norwegian princess' ex-husband some years back. They could have said he had a heart-attack or something, but openly told that he chose to end things himself. I am NOT suggesting that this happened in Jacks case!! I'm just saying that being open and let people show their love probably helps the ones who are grieving too (and it prevents speculations).
I don't read gossip -pages, don't follow "influencers", and hardly watch any reality-series. I don't think people should share absolutely eveything on social media. I do believe in openness and dialogue. To share emotions. We are all humans
