I really do admire your work ethic. 👍
I've just come back from being in Spain for five-and-a-half weeks, but three weeks before I was due to go, I was offered the opportunity to join a tribute band, I spent those remaining three weeks learning the set.
Before I went, I enhanced the bass in all the songs so I could hear it clearly when I was laying by the pool on my sun bed, I listened to the tracks over and over again worrying that I would have to start all over again when I got home, but I was pleasantly surprised because when I started going over them, I felt refreshed, and my playing was much more fluent, so maybe a break can do good.
I'm not saying it would work for you, but it certainly did for me.
