I’m struggling to work from home now that my children are teens. They constantly need me, and I can’t get my work done

I have five children, ranging in age from 6 to 17, and I’ve worked from home in some capacity since I was pregnant with my first child. I pushed through many years of burnout and even sacrificed my own health to achieve my dream of working from home because I truly believed that eventually, when my children were older, my life would settle down, and work would get easier.
