Here is a different perspective...I "rescued" my son in 6th grade and, though I would do exactly the same thing again for that year, I decided NOT to homeschool 7th on. It was just too much for me to be mom and teacher and tutor all at the same time (he has ADHD and I struggle w/ depression). I would be a great teacher for anyone else's kids, but being that wrapped up with one (of three) was too much.
7th through now, 11th, we have found a number of teachers who see his gifts and his brilliance and capitalize on them, a school w/ a principal who is more than glad to work with us (and surrounds herself w/ quality staff), an ADHD coach/counselor w/ a great relationship w/ our son, and many adults who simply enjoy our son's company. I, alone, could not offer all that for him.
If you do homeschool, I would caution you to make sure, especially being a single mom, to balance YOUR life so you get out and about and nurture your soul, hobbies and friendships. Perhaps look for alternatives that can serve you/your kids as well (other schools, counseling, adult mentors, friend groups, etc.)
You will do great at whatever route you choose. Go boldly, with a smile!! --H.
