If this is a real post.... the issues that you have are not caused by wealth and wouldn't necessarily be resolved by wealth unless you specifically recognise your issues and use your wealth to help you resolve them.
Feeling incredibly isolated isn't to do with wealth. It's to do with your chosen lifestyle, where you live, the society/culture that you're in.... all things you can choose to address.
Your children don't inevitably need to feel intense pressure or stress. That's coming from you, your friendship group, your chosen society. Don't act like it's outside of your control!
You say "sacrifice", where you mean "choice". Missing out on things you wanted in order to get other things you wanted more are normal choices, not a matter of great sacrifice. Nothing you mention is a massive sacrifice in general terms. If you now regret your choices, then make better ones from now on. Reflect a little on why things you thought were important now aren't. Again, none of this is caused by or solved by wealth.
Of course being average in a wealthy country is fine, and not a horrible position to be in. Being below average in a wealthy country is also ok. But being very wealthy is clearly still much more advantageous! You would be very silly to think that it's not.
Also, "the average person seems to believe it’s endless bliss, no stress and every rich person is a genius who never tires and never feels sad." - this is bollocks, people don't think this. But they recognise that if you do face significant issues you have much more choice in how to handle those issues that the average person doesn't have access to.
