But I'm not sure how we can generalise that people aren't seeing improvements in their happiness and mental health. Personally I'd say mine has definitely improved since I've become more mindful as to what I spent time and mental capital on.
This from the BMA:
COVID-19 has only accelerated this trend, driving an increase in the number of people who are in contact with secondary mental health services. Mental health services in England received a record 4.6 million referrals during 2022 (up 22% from 2019), with the number of people in contact with mental health services steadily rising. As demand goes up pressure will be felt not only on mental health services but on general practice, at a time when GPs continue to face the wide-ranging impacts of the pandemic.
And of course, there's a massive increase in child and young peoples' mental health issues because children became isolated during Covid. Friends who teach (secondary and HE) report major issues with MH and behavioural issues (young people unable to navigate their way through ordinary social and work interractions). My local university's student services department is constantly advertising for people qualified to offer MH support.
Not a lot of signs of improved happiness and better MH from where I'm standing. I'm someone who, left to my own devices, probably wouldn't socialise very much. But I have a very social partner who pushes me to go to out and so stuff with others and almost always, afterwards, I feel lifted by the contact with others. Every time I read the research showing how important socialising is to good mental health I feel very lucky to have a partner who tests my boundaries.
I think that if you start to think of friendship as 'investing mental capital' you are in choppy waters. My most enduring and rewarding friendships are with two women whom I would never have thought I had much in common, and would never have spotted as being the remarkable, strong and supportive people I've come to know. I think the best friendships surprise you and do sometimes involve investing mental capital — because all good relationships require give and take and stretching yourself.
