In Greta’s mother’s book, they say she was formally diagnosed with severe anxiety, OCD and asperger syndrome. It has manifested in eating disorders and severe withdrawal before the age of 10.
This diagnosis is also backed up by the fact the non-famous sister has similar diagnoses.
Yes Greta's got mental health issues and her parents should be arrested for putting her out there as they do. That was evident when she spoke awhile back...her OCD, naivete and fearmongering is her problem as I see it...she scares 'herself' working up like this... autism is not a super power as she believes... It's a disorder.
