I just read your original post and felt your pain. Some days, months, years are harder than others, but if you had not been homeschooling you would not have been able to do all of those things you did. I have a homeschooler friend with 10 children 2-23. I remember one day I had asked her if she could watch my kids so I could work, but she had other things that needed to be done. Her reply was that if she couldn't teach her children that is was important to help other people she wasn't teaching them at all. That's always stuck with me.
Have you tried Classical Conversations? We were introduced to it a couple of years ago and it has really helped us to keep our focus. As long as they were learning the memory work, they were learning something in every subject. The history is to a song, there are songs on youtube for the science memory work. If you look it up you will find that they say you have to go to a class to do it, but not the foundations part. All you need is the Memory work CD. I have compiled written pages for each week of work so the kids have it on paper as well as listening to the memory work. If it is something you are interested in I would be glad to share my files.
Praying for your endurance. Hang in there!
