Holy shit I feel like I'm going insane here
I just spent 2 hours trying to setup my UI to be "good" (read: not as shit as the default), and I'm at a point where I've just disabled everything new because none of it fucking works properly, or is a nightmare to understand.

Guides are either outdated (addons no longer functional) or are actually for Retail.
And HOLY SHIT, the end result of this colossal waste of time is that my game is now fucked up. For some reason the font has changed, damage numbers sometimes aren't appearing, and things just feel "off".

Can someone please just tell me how to make my game look like the right side of pic related? Blocks that clearly show health, and ideally incoming heals and such.
