I feel exactly the same as you do. Homeschooling is a choice that we have made for our family, and when it gets rough, we dig in, put our shoulder to the harness and plow through with humor and LOTS of prayers.
I'm personally convicted that the paradigm of public education as it stands is not palatable to our family, and I see little if no evidence that it will ever change.
ETA That I will add this caveat: Every year at the end of the school year, we re-evaluate where we have come, where we are, and where we will go next year. If it ever comes to home education not working for the family or my daughter, we will of course find a way. I'm not hard heartedly going my own way for my own personal convictions. If home education is NOT the best for our daughter, we will then evaluate our choices at that moment. For the foreseeable future, we plan on home education all the way.
