These are helpful posts. I guess other than being a model for my students in terms of stability and so on, I just want what is going to best nurture their growth (and keep my studio afloat, too, since I will still be depending greatly on this income). I just don't think it's best for them if I am sporadically present, though, I don't think I am in danger of that, exactly, as of next year.... it's just looking like my life is heading that direction. It is one thing for a Uni teacher to leave his/her students for times, but it's another for somebody like me to leave my students, especially my little ones, for times.
But, I just thought of something along the "sub" idea, if I needed it. I do have one student who has studied music in college and is getting to know "my system" of teaching, she also already teaches her own students, too. Perhaps I could consider her if I needed it, she would be perfect

. Thanks for that thought, thalberg !
After I made this thread I went and wrote out a tentative teaching schedule for something that might work a little better along with some of my performance commitments, and I even already asked a couple of my students about the times and they seem to think it would be fine (I am breathing better already). I will keep working on that a bit.
I will say that when I was studying in Uni, I was one to appreciate my own teacher's commitment to me, by way of their commitment to their studio in general. I actually have noticed some pretty big differences between studios whose teachers are almost always present (while maintaining a performance career), vs. studios whose teachers are often shifting and cancelling lessons. I would rather be the former, no doubt about it.
But, you are right. I can be an example of a performer, too, and that is great for my students as well. Ideally, I just want to find a way to work it out so that nothing is truly suffering due to something else being present -- I think that would eventually just rip me to shreds.
