If you apply eawerner’s suggestion, you are ahead by a minimum of two days. 
But, I know what you mean. I’m “behind” at this point on paper. I am having to learn to keep my shoulders and neck “loose” instead of tight. Those habits are especially detrimental after a wreck involving whiplash, btw. UGH!
A few things I’m trying to remember is to let my arms hang down, almost limp. BREATHE! (I’ve held my breath and kept my shoulders and neck tense for more years than I can count due to the very same reasons you’re dealing with at the moment.) I’ve started reminding myself that I’m not facing physical giants, walls, or armies. I’ve intimidated myself and been intimidated by others by setting unreasonable, sometimes unnecessary, or unrealistic goals for myself and my children. I remind myself that God is right here with me, with us. He knows the plans I’ve made, but sometimes He adjusts them to help us learn something He thinks is more important.
I’ve always been a paper planner until this year when I started using the CMO. I stepped away from the paper planner for a time, but that paper does “feel” more secure, more controlled….that happens to be a problem for me because I tend to freak, fret, or feel like I’ve lost my land legs without something to hold in my hands that says “This is going to be exceptional.” But, that ends up destroying me if I can’t pull it off. It ends up making me “see/think” I’m not able to pull it off, or NOT exceptional. That’s not helpful because then I dwell on it. Some might push harder to double up. I used to when I was younger. The longer I’ve homeschooled, the more challenges have cropped up and I haven’t had the energy/endurance to do that anymore.
I really enjoyed reading eawerner’s perspective. I hope to have that perspective become automatic sooner rather than later. It takes into account fruit, truth, and reality. Instead of focussing on what hasn’t happened, look at what has been learned.
For me, it’s been a serious matter of learning to say “no” to some subjects/activities, even history at times! GASP!
I don’t know how many children you have, or old they are, but if they are young, and if your state doesn’t require all sorts of subjects, taking time in the three Rs and habits will help you make up for lost time later down the road. The children will be able to study on their own and learn all sorts of things you may feel you might miss now if you fall behind.
I’m not saying to get lazy about it, but if you don’t learn to let God be your strength in homeschooling, you’ll run out of steam on your own and then you will find yourself truthfully behind because you won’t be able to follow through on much of anything due to exhaustion (I know from experience.)
You are likely planning too much. Instead of planning a year, just plan a term, giving yourself room. None of us learn as scheduled. Math concepts might take longer to understand than planned. You’ve already recognized this, I’m assuming from your post. Revamp with a much simpler routine to begin to see what is being completed. Then, add in things you miss studying and realize you can fit in without overwhelming everyone. You might do just a few subjects and leave out the pretty CM extras. Save them for off times and do a day of fine arts, or science experiments, or watch plays and documentaries that go along with the overall plan for the year. It will feel like time off because of the change of pace, but you will be able to “count” it and feel good about it while relaxing.
I hope some of these ideas help a bit.
