I agree with Jackalyn. The only thing sticking in my mind was the arguments and RD not phoning an ambulance, she sad she 'didn't have a siezure' but it seems most people are not aware of the different types of seizures and the behaviour they can cause. The arguing can be explained by Gaia not being in a good state mentally.
I'm not sure if she'd have time to call an ambulance. Sounds like she was in and out. Then where would you direct an ambulance once she's taken off? Also the behaviour isn't what most people would associate with epilepsy. If someone came to my door freaking out I don't think I'd know what to do. I think the closeness of these families is being exagerrated as she had to get another family member to contact her parents. I know from a friend's experience that when a family member of theirs was acting in a extremely bizarre and upsetting way during a time when when they were trying to get the right dosage for anti-depressants, 111 were not interested. As soon as they realised they weren't suicidal they were told to get in touch with their doctor after the weekend. Eventually after much pleading they secured an out of hours appointment, but they weren't willing to send an ambulance.
