It’s not about her physically being there though imo. She might physically be there but she’s obviously got her nose buried in Facebook, updating an audience like her son’s life is an episode of Eastenders and the nurses are the baddies ready to pounce and switch off. And while this fighting mentality may be helping her now in the short term (I don’t doubt it must be lonely in that room day in day out with very limited human interaction from her loved ones) in the long term it’s probably something she’ll come to regret especially long after this story fades from everyone’s minds and the grief vultures pecking at her start dissipating onto the next sick kid - because what then, what does she have to show of her son and her son’s ‘fight’? Very little, I’d imagine. I think for her sake she needs to just switch off the phone and BE there with him, take him in, go over memories, make as many peaceful memories as she can with Archie as he is now because once he’s gone that’s when she’ll be consumed with the guilt, the thought that she could have done more, that her son’s last days on this Earth were filled with venom and not love.
