I, too, understand your dilemma... I taught HS science for 30 years, retired, went back to school to become a PTA and am now back to work! I didn't touch fabric for two years... That's the bad news. The good news is, like so many others have shared, you will find a routine, and while you probably won't get to spend as much time quilting as you would like, you WILL get to sew.
The other important thing to remember is that your work with students is SO IMPORTANT!! To have someone in their life who cares for them, as you clearly do, is powerful! Remember, you are impacting lives in ways you may never realize... every moment with them counts...
I will remember you in my prayers...
