It's unfortunate you were affected that way by it. I can definitely see people's point when put that way. I'm surprised how easily the bizarre message is brushed off by content creators and streamers to this day. Though I've seen some people comment something similar on reddit lately.
I suffer from depression myself but tbh I ended not being affected emotionally at all by EW because the moment Meteion started her report I just thought "Oh no. They're going full pretentious and focus on the question of the meaning of life to make simpletons think Endwalker's writing is deep, aren't they...?" and it was like all the remaining channels of immersion with the MSQ shattered right there, and I was just continuing to make fun of MSQ with friends from there on.
This reminds me.
While everyone has always seemed to be just looking forward to new nations (which are all going to be glaringly obvious FFXIV versions of real world non-european nations for social media buzz sake) I always wished they would just add more side-stories with quest chains related to each starting nation's internal struggles more. Without Ascian or Hydaelin nonsense hijacking it. Get Matsuno to write those, while the rest of the Walt Disney tier stories that seem to be more popular with the stans can go on without interference.
There is so much lore and so many plot points they haven't done anything with in the 3 nations. And when they do, they seem to shit all over the potential (The Sil'dihn Subterrane storyline). Seriously, leave that kind of thing to Matsuno or some writer that isn't afraid of making more mature scripts.
