This is what it comes down to, unfortunately. Due to circumstances (which I'm sorry about) you couldn't provide what you felt was necessary for your daughter. This happens! But one can't make a general rule out of it. I would suggest looking into homeschooling societies, though. There are a lot of them. Homeschooling, at least in the US, doesn't necessarily mean the child is locked inside with their parent all day and isolated from their peers.
