Welcome. No, you're not alone. Couple of quick comments:
- Asperger's. Could be your friend is mistaking the overintensities that often go with giftedness for signs of an ASD, could be she's seeing ASD and is right; very hard to say. The book
Misdiagnosis is worth a look.
- School. Don't panic. It isn't necessarily going to be hard. Would home educating be an option for you? Even if it wouldn't be a preferred option, thinking of it as possible helps take some of the stress out of school negotiations, for some people.
