15 year old constant disruptive behaviour..

Hello Wave I’m new, first time I’ve ever joined anything like this.

my son is 15 & was diagnosed with ADHD, Autism and Learning Disabilities at 7, due to a micro deletion in chromosome 16. Since his diagnosis he was then placed into a special provision where he began to thrive which was fantastic! 

However since his younger siblings have gotten older (currently 5 & 8) life at home has become unbearable due to our eldest sons behaviour. 

He comes home from school and he’s rude, shouts, swears, calls his brother’s names, threatens them, is verbally and physically abusive towards them until they go to bed. An adult must remain in the room at all times to ensure the safety of the younger ones which is not practical or sustainable. 

We feel like we are at our wits end, we have reached out to so many people/departments and have got nowhere, it’s got to the point where my husband and I thinking about separating just so that we can keep the little ones safe and have somewhat of a break from the eldest. 

I know some of his behaviour could be impulse driven, he refuses to take his prescribed medication and he is generally well behaved at school. 

Thanks for your time, any advice appreciated Slight smile
