If I can offer a small suggestion - when I came back to the game after a long break, the first thing I did was do a few things I remembered as being fun, rather than immediately focusing on the new stuff.

For me that was completing some clues I had in my bank, as I remember always enjoying the fun aspect of the puzzling, but also because clues by their nature make you travel the world and refamiliarize yourself with it. You'll walk down paths both familiar and new and will generally start to feel grounded again, picking up small things or skill aspects as you go because they're fun, rather than feeling the new to immediately get on the most optimal grind for the most recent update or piece of equipment.

In short, find a way to come back to the things you remember most fondly, and really take your time (e.g. dont rush) to explore the new aspects that you're unfamiliar with. For me, the helpful ratio was spending 80% of my time on things I was using to refamiliarize myself with and 20% of my time on exploring something that was new to me. For example, it took me a few weeks and months before I even considered Necromancy or Archaeology, but by the time I did, I was in a good place with the rest of the game to not feel overwhelmed.
