I figured I could use some prayer and advice from you all...this group is such a blessing

Our oldest daughter has had a difficult year following a family trial which shook her faith and left her extremely worried that something would happen to either me or my husband. We've prayed with her and for her, memorized scripture, sought wise counsel, read books etc. but it was getting so that she didn't even want to be down the street or dropped at an activity, things that were previously not a problem for her.
We were surprised this summer that it seemed that the Lord was leading us to put her in school for a year. I hope we heard Him right on this! It has actually been quite helpful in many ways and we are so very thankful to have had the option of this particular Christian school.
But, it is a "traditional" school and she is beginning to be bogged down by homework, lifeless textbooks, tests galore, focus on grades. She is doing well academically and socially, but she comes home exhausted and is beginning to dislike learning.
We've had remarkable peace about having her in school the past 5 weeks, but all of a sudden both dh and I are both thinking that it might be time to pull her out prematurely, or consider some sort of a part-time option. If only we knew for sure what would be the best for this sweet daughter of ours.
I'd like to ask for prayer, and also if anyone has any insight about transitioning in and out of different school situations i'd love to hear. Or any advice about helping children who are prone to worrying/fear.
I write this humbly, knowing that a year or 2 ago I might have felt judgemental about a family who made the same choices. I've realized that perhaps I was entrusting my dc to homeschooling more than I was entrusting them to the Lord, and that has been a good learning process. But we still are quite commited to homeschooling our dc, and have felt God's calling to do so until further notice. So, if we keep dd in school for the whole year that means a real bouncing back and forth between the classroom/textbook approach and the homeschooling/CM approach.
Thanks for reading this rambling post.
Blessings,
