This is true - many parents just plainly do not recognise more subtle signs of autism or adhd or ocd etc.
op have you spoken to her primary school teachers from each year to find if anyone else saw signs but didn’t mention them to you?
However, I’m actually very shocked at how many people are saying their kids were diagnosed with autistic burnout, despite having zero signs, because they have burnt out/broken down. Even people who are autistic but capable of masking to this degree can have a breakdown without it being to do with autism.
Kids can have whole lives going on at school that they never tell their parents about. They can be bullied and you don’t know. They can be being SAd by a family member, and their parents don’t know. They can have a teacher humiliating them and parents don’t know (or believe them). Or they can have never dealt with the death of grandma and have death anxiety, which becomes morbid thoughts, which becomes depression. There’s so many things that can build up to cause this breaking point.
At some point this comes to a head and they break down - maybe you’re eleven and a combination of pre puberty and stress collide. Or you’re 15 and people think you’re just being a teenager then it gets bad and you end up drinking and self harming and pregnant. Or you’re 23 and you’re doing drugs and sleeping with strangers and going no contact with your parents. Assigning it to autism doesn’t address the underlying trauma or stress build up. Even if there was indeed autism being masked.
And why autism? Sensory issues don’t always equal autism. Adhd and ocd can both present as this and ocd behaviours are fiercely hidden by kids, has op been given any ACTUAL understanding of any of these conditions? How is she meant to know what she is looking back to try and find? If she has no experience of them, maybe she missed behaviours or maybe she didn’t but how would she know?
and 100pc PANDAS needs to be ruled out. And this sounds incredibly extreme and sudden. Writing it off as ohhh she was so good at masking now it’s dropped and she’s burned out is not good enough frankly.
