If at all possible, I’d try to arrange for a break.
A lot of this sounds like it may stem from burnout (before getting into any more long-term conditions). Taking a break probably won’t help you see your job in a new light (some jobs simply suck, or aren’t a good fit for people personally), but it could give you time to rest enough to look for other opportunities. However first and foremost any such break should focus on resting and recovery to get you to a better state to just be well and happy.
Once you know you can sort out breaks and recover, you can set aside more time to look for opportunities. Right now it seems almost like this may be among your best options: carve out breaks for yourself to rest and recover. Once you’re feeling better, take time you’ve reclaimed for yourself to seek out opportunities to change jobs and improve your work situation.
Personally I dislike anything with -verse involved because big companies have run it into the ground and then some.
The boring, dry ways of describing them work best in my opinion.
Federated forums is the driest, most technical and to the point but not very telling.
Swap out forum for link aggregator and you have similar, arguably even more technical (certainly more of a mouthful).
Connected/linked forums might be more approachable, more readily conveying how these are separate forums but networked together.
Cross-forums may work as well to the same end, but not sure how immediately understandable cross may be in this context and outside of gaming spaces.
Whatever the case I kind of think this has things backwards. What’s more important than describing and talking about the backend tech is pointing people to any of the sites built with them that have anything of interest to them to bother with. I can’t think of anything online I’ve ever gone to or used because someone told me it was using Apache, Nginx, phpBB, or like an Open Source Web Server or using such and such CDN.
The reason why is simple: next to nobody talks like that. The only people that might are deep in web dev.
