I think teaching just becomes more and more "stuff" for us to do. Always adding things on are plate and never taking anything off. So I can see that even with a ton of experience you would feel less on top of it than in the past. Best of luck to you :)
Happy to have you! I have a podcast episode (Simply Teach episode #1 with Elmer Nealy) he was a teacher that taught a combined class. May have some helpful ideas :)
