I've got tinnitus, have had it for years, and I tend to listen to music when I sleep to drown it out a bit. Soft music is better than what is effectively a constant minor static-y noise I guess. Recently I've been listening to Lillie's theme for it and it's reminded me how much I treasure Gen 7. I do get the distaste for it, but I really appreciate what they did with the story with Lillie. When I look in Bank and see a Lunala called Nebby, I have an emotional connection to it a lot stronger than any of the other legendaries I've caught in main stories.

I'm now 27 and he's still with me. He's very important to me and has always been a legitimate comforting factor in my life for me, consistently, for so long. I'm really excited for Sword and Shield in part because I'm British myself and it almost feels like he's coming to my home region for the first time in a way, after almost 15 years of travelling together.
Anyway, I hope you get well soon OP. Dealing with physical pain sucks ass, but there's always a reason for it so there'll be an answer and relief soon enough.
