New unschoolers are often afraid. They're afraid to keep doing what they're doing; they're afraid to change. Sometimes to calm someone I have said "It's not like moving to Mars. You will still live in the same house. You'll still be sitting in that same chair."
Something that allayed my fears when I had babies still works years later. When I'm fearful or worried, it helps to smell the top of my child's head. If you find a natural opportunity to hold or hug or bend over your child, inhale the scent of his head, slowly. Don't worry if it's an unbathed eleven year old. Just do it with love and gratitude, and you might find yourself in that moment, touching your child gently, remembering who you are and where you are.
I don't have a page on fears. This one mentions the benefit of smelling a child's head, though: http://sandradodd.com/peace/noisy
