Came here to suggest Akagi, it might also help to play a little Mahjong Soul to understand riichi mahjong. It’s not essential, but rewatching Akagi after learning how to play was an enhanced experience.

Too right, mate.

As an Australian, why bother importing “y’all” when everyone is already “mate”?

A couple of random suggestions:

Summoning Salt - Video essays detailing world record speedrun history across a variety of games. Videos are easy to understand and assume you aren’t intimately familiar with the games in question. https://m.youtube.com/watch?v=i1AHCaokqhg

RRC Restorations - A Scottish bloke that does really in depth restorations of mostly cars and motorcycles, very relaxing and a joy to watch without any flashy filter. Just a super talented guy doing cool things in his little workshop. https://m.youtube.com/watch?v=JJSjy4OciLs

Motion in Art - Film essays similar to some of your other favourites that might be of interest.

Art Deco - Analysis, investigation and explanation of art, including the history and context in which paintings were made, themes and motifs, and details that you almost certainly missed when looking at art as a layperson. https://m.youtube.com/watch?v=m3hM6Qw8Nf4

Fredrik Knudsen - Making the series Down The Rabbithole, which are dives into a variety of topics, including tech and history. https://m.youtube.com/watch?v=UCgoxQCf5Jg

Lemmino - Video essays on conspiracies and mysteries, all are very interesting and worth watching. https://m.youtube.com/watch?v=5u7euN1HTuU

I don’t think there’s magic one size fits all answer to this, it really sucks you have to deal with it. Avoid destructive behaviours like drinking until you pass out etc, they won’t help in the long term. Do you have any friends IRL you can call on?
