How do you know she’s autistic? Maybe she’s depressed, experiences severe social anxiety, or something else of that nature. I see no reason to jump to autism as the explanation, there just isn’t enough context.

I’d say the stuff about having meltdowns and the way it’s described points toward autism, particularly the Christmas incident, but it could be something else. I say this as someone on the spectrum myself, though far more able to function without support than the girl in the story.
