Thank you again for all the replies! Sounds like most agree trying out dungeons, trials and raids would be time well spent and I think it may indeed be time to get over this fear/anxiety over trying new things that carried over from my time in WoW. I still get filled with dread when queueing for something I've not done before out of fear that I'll make mistakes and be showered in insults, something that has yet to happen here. Just yesterday I did SoS as part of the story and it took us an hour to clear it, yet at no point did anyone berate or point fingers, rather discussing and giving helpful tips.

I think a clean slate for Endwalker would be the best gift from me to me that I could make. And maybe I can work on some other jobs/gathering along the way if time permits, who knows!
