I see reddit mentioned by multiple people. I think the sub https://www.reddit.com/r/financialindependence/ might also be a nice fit, as it is about how to become financial independent (already achieved by OP) and then what to do after (retire early? how to manage the money? etc)
I'll second this, all of the FIRE subreddits are not a great place to discuss your situation. Those subs are full of people saving about 40-50-60%+ of their take home and slowing building wealth overtime.
