I actually don't know whether or not being in solitude amplifies the issues. I am alone with no contact now, mostly by my own action of ghosting people. This comes in contrast to a few years ago when I was working and socialising most evenings to sitting in an apartment. I use my physical voice one every three days when I go to the store to buy groceries, it surprises me every time I hear myself, its only a handful of words I say, not a conversation. Sinead though had a particular fall from grace though as her meltdown was particularly public. I do have to be a bit wary of her video content as she is still quite active in the music scene going to a lot of festivals and performing. She was on UK TV a few weeks back giving an interview on converting to Islam. So maybe she was a bit isolated then but certainly not now. I also get wary when celebs do certain things as cynical old me says 'self promotion'.
