Plenty of people will be fine but it's wishful thinking to suggest there won't be a big surge in mental health issues.
Absolutely right. It's already happening. There's nothing new or surprising about that. When the economy is in meltdown and people aren't working or even allowed to socialise as they would do normally it has a massive impact on mental health. And for those already being treated for mental health issues, like anxiety and depression, this is making matters worse.
I also understand there's a big surge in people filing for divorce. I like to think that's a good thing - and I know that may sound very harsh, but I don't mean it to be. I just think that some (possibly "many"?) couples co-habit under the same roof for years, living separate lives. They aren't happy with each other, but it's a convenient arrangement and the alternative seems far worse than just carrying on.
All this "social distancing" stuff puts a lot of pressure on relationships like that, where they can no longer slope off to the pub out of the way, or even go out of the house for any length of time. They are incarcerated in a life they normally manage to avoid, and things are expected of them, like doing their fair share of household chores and looking after the kids. Most of all, they are with their other half for large amounts of time, something they may not have done for years. That creates a lot of pressure in a relationship. And the reason I say, I like to think it's a good thing, if it leads to filing for a divorce, is not because I think divorce is a good thing. Thankfully I've never been through it myself and have no desire to, whatsoever. But I do think it's a very bad thing if you waste your life doing something that doesn't make you happy, or spending it with someone who doesn't make you happy. So, this period that we are going through may just test a few relationships and force people to either make more of an effort with each other, or take a decision for themselves which will ultimately lead to them both being happier.
