But Lookout doesn't believe Sheila was ill. I've not been able to get to the bottom of this but I can only think it might have to do with mimicry being the sincerest form of flattery, ie she was reflecting June's illness -and we do know that children copy parents- although June wasn't a schizophrenic.
I do believe that Sheila suffered from depression though and probably because she couldn't understand why she was feeling the way she was,it was ignored while she struggled to get on with her life. It was only when she was in Japan,modelling,that she must have realised that not all was well and wrote to Colin to book an appointment for a psychiatrist.
I don't believe she was as ill as had been made out, her needs had been misunderstood.The girl was by no means stupid. The medication dished out to her had wrecked her. I'm a firm believer in getting to the cause rather than treating the symptoms. "Attacks" that Sheila suffered could have been sheer frustration,bordering on temper,similar to a child with ADHD or Aspergers where certain situations cause a meltdown,but it doesn't mean that they should be given the strongest dose of whatever as it only acts as a temporary measure until it's repeated again,which furthers their problem because of the reactions from these drugs.
Even the use of Diazapam causes hallucinations in many,but for others is an answer to severe anxiety,so they're not for everyone,and giving too much of these drugs is just as bad as giving too little.
Until anyone has seen a patient who has been given too much of a certain drug,particularly to treat anxiety and behavioural problems,then you can't comment on their toxicity or effects on that patient.
