I'm dx'd level 2. I was diagnosed until later. It's hard to be an autistic kid, full stop. Nothing but empathy for you and your daughter.

If it's any consolation, childhood years can be very tough around that age for autistic kids, but many of us find significant communities once we get online and around other autistic people our own age. Many of us go on to be very successful and happy adults once we find our niche.
