I am so worried and would really appreciate some advice.
My niece has never been diagnosed, but we believe she is on the autistic spectrum. She was diagnosed previously with ADHD.
Her behaviour has recently spiralled out of control. She regularly leaves the house and goes missing for hours.
She has been self harming (cutting wrists, hurting her face etc) but we believe it's for attention as she shows friends the wounds, and even cut in front of her friends.
Even more worrying, she grabbed the car keys and started her mum's car yesterday.
She regularly screams for long periods, outside late at night (so suggesting attention seeking behaviour?).
My sister is at her wits end, she can't calm her dd down. Then the following morning, her dd acts as if nothing happened the previous evening.
She has recently started her periods, but even before this, her behaviour has been difficult for years, but nothing on this scale.
My sister is very worried that she will hurt herself badly, be a danger to herself.
She has an appointment with the local CAMHS team, but to be honest, they have never taken an interest before and my sister feels that they may be unhelpful again.
Is there anything else my sister can do?
