S.T.
i too spent a lot of time gnawing my fists, terrified that i was going to ruin my kids.
fortunately kids are pretty resilient, and if you're homeschooling from a good place (and it sounds as if you are), you'll figure it out. you really, really will.
you will change your philosophy. you will change curricula. you will abandon your curricula and create your own. you will join groups, leave them, and start some. you might abandon them too. that's all okay. don't think you're going to have it figured out, and don't get too worried about missteps. you are going to learn more about your kid, and yourself, than you ever thought possible.
and you might even find yourself with MORE free time. once you find the right group, your girl will have opportunities for adventures and events that will allow you to send her with trusted friends and groups and let you have an occasional free afternoon! (of course you'll pay for it by having hordes at your house for a shakespeare afternoon or math games or nature walks or science projects. but it's worth it.)
independence and socialization will happen. unless you're forcibly keeping her at home and refusing to reach out to local groups and resources (and yes, some homeschoolers DO that) you'll find more 'socialization' than there are hours in the day.
it'll be good, ms. M.. good for you. good for your daughter.
keep coming back here when you have questions.
ETA, great jumping jeebies, please don't listen to the wack advice below suggesting that if kids don't get up at 6:30 every day they'll never be able to do it. it's nuts. people get up when they need to get up, and rest when they need to and can. my homeschooled kids got up before dawn if there was something going on, and stayed up til dawn and slept til noon if left to their own devices. they have both adjusted to college and work life just fine. and my childhood years of getting up for school and work haven't made me love leaping out of bed early. kids are way more nuanced, adaptable, sensible and intelligent that some parents can understand.
