I have a reasonably small number of friends on Facebook.
Can think of 5 instantly who post regularly about their own MH issues and MH support in general.
2 of them have very serious issues (depression for one and bipolar for the other) which have led to hospitalisation. They regularly post about how difficult they are finding life.
Yeah, other friends will post a big old boast when their child does something they're proud of. I like to see it. I care about them, I care about their kids. Same person next day will post and say "shit - is it a dress up day tomorrow then? Anyone got spare "
Plenty of self deprecating humour.
Just choose who you have on Facebook.
I think it's a bit naïve to say "Scandinavia, maybe?". There are loads of great people in the UK with lovely attitudes. I daresay there are some competitive show offs in FI, NO, DK, SE...
Not sure how comparable UK and Australian private school systems are. Aren't the Australian ones far more common place and cheaper? That's going to skew the profile of the families and personalities using them.
I know 3 people working in Sydney who have all said the long hours culture in their offices far exceeds the companies they worked for back in the UK - all large international corporates, but not banking.
OP, you're not going to move to a Scandinavian country or Australia in the short term I presume? Don't fall into a trap of expecting some untrue stereotype of everyone in the UK. There are people like you and not like you in every country.
Strip Facebook back to your genuine friends - and be happy for them for their happy posts.
The grass is greener where you water it.
