My best suggestion is - afterschool (you say that you are exhausted meeting her needs, and that is why I am not suggesting homeschool).
This generally works best in half-day formal educational programs (Kindy or preschool). IME, anyway.
Why?
Well, ashley nails this one--
The only problem with afterschooling is that it interferes with extra curriculars and it comes at a time when the child has had a long day and is tired.
Remember, those ARE your child's opportunities to meet peers who share his/her interests and ability. If you limit those for the purpose of... hm...
forcing him/her to withstand an inappropriate educational environment daily...
I'd be certain that what s/he is getting out of that educational setting is worthwhile. It might be, if the social setting is lovely and fills a need for your child. It's also possible that it will become less worthwhile over time.
There does come a point even with a fairly exhausting child at which it's LESS work and more beneficial to everyone-- to homeschool rather than to afterschool.
You may also find that as your child outstrips your ability to meet his/her needs educationally, that you have to find other sources. That means $ and time to spend with those others. School can begin to seem like it "gets in the way" of your other educational opportunities for children like this.
Afterschooling can make a nice bridge to full homeschooling, though, and it will give you an idea how hard it would be on you (and your child).
