Hi Amy,
I also have a 10-year old girl who is immature compared to the girls her age and has difficulties with friends because of her impulsivity and anxiety and because she simply likes things other girls find too "childish". After much debating, we have now decided to homeschool her for middle school, starting from next year (Fall 2015). She wants to homeschool, which is quite telling of her discomfort. I am reading all I can about homeschooled adolescent girls and about ways, thoughts, pros and cons (I haven't found the cons yet ....) of homeschooling. I wish you (and myself) a serene journey.
