I don’t want to speculate and it isn’t my place to diagnose, but I know Sophie reads here so I just want to say that if she suspects anything at all is happening, seek medical attention.
Just from my experience I was diagnosed with epilepsy as a teenager after having two tonic clonic seizures. I was also noted to have suffered from absences, but my parents had never known that absences were a thing that existed. I had been treated as a child for glue ear to explain why sometimes I didn’t respond. It’s only now that I realise that the glue ear may have been a problem, but it was ultimately hiding the undiagnosed epilepsy. If only I had been diagnosed sooner I might have had better seizure control now.
We see a tiny fraction of what happens, and maybe it is nothing. Maybe things have been looked into and Sophie doesn’t want to post about it which is entirely her choice.
