We used to live in Colorado Springs and in Denver, so I'm familiar with the school situation in Colorado.
Have you looked into cyber schools (also called virtual schools or online schools)? They're free public schools conducted online from home. Colorado has an active, vibrant cyber school scene.
The pluses to enrolling in an online school are several. The student is accountable to real teachers, and joins an online student community. The schools have counselors and academic help available. There are scheduled class times, but all classes are recorded so a student can watch the class later if he or she misses the original time, or can watch the class again if there are concepts that need more practice. And there are lots of extra help sites offered by the school, for students struggling in a particular area (offering practice, sample quizzes, additional lessons).
Also, there are real in-person events. My daughter attended Destinations Academy of Colorado, and teachers held meet-and-greet in coffee shops. There were bowling parties, and field trips to museums and pumpkin patches and cultural events. They hold cyber school rallies at the state capitol where students can meet other cyber students, and meet their senators and representatives, and see a senate session in real life.
There are no fees, tuition, or costs except for an occasional minor lab equipment fee (the student will receive materials for a project in the mail, for example, but those fees are very very small).
It makes such a difference for a student to have teachers to answer to who are not his or her parent, when there are struggles. The students become accountable to real teachers, and to other students, and to principals and staff, from the safety of home.
My daughter was significantly behind her grade level, due to her medical problems. We met with the staff in person when she enrolled, and they designed a program just for her. I have a degree in education, but I was so busy managing my daughter's many medications, hospitalizations and appointments that although I COULD have taught her, I didn't have the right amount of time to also create a curriculum and homeschool her. So the cyber school was perfect.
We set up a school area for her. She would check into her classes, do her homework, and her counselor would call her twice a week.
It sounds like you could benefit from something like this.
Here's a link that lists a lot of free public schools in Colorado that are cyber schools.
