How to overcome traveller regret?

Hi all!

This is not another "Hoyo please let us switch travellers" post, I've gone through a lot of those already.

I just need some anecdotes or words of wisdom about it, I have this intense regret for picking Aether on my account 3 years ago. I'm f2p and proud of everything I've got on my account, I don't have enough time in a day to really be serious about a second account but I guess I could try, still though my main will always be this account with Aether. There are some positive things like abyss Lumine is super cool! But maybe I'm not focused enough to make that feel like it's worth it.

It just feels like there's something constantly not right, like there's a stone in my shoe or something. It's very uncomfortable, I just wish I could be Lumine.

Anybody have any words of comfort or copium so that I can live through this regret and just be able to enjoy my experience again? I can't change the past, but I need to learn to live with it and I just don't know how right now. Thanks!
