Help and support

Hi Wave everyone 

I hope you’re well. 
I’m looking for support please in how I can assist my 7 year old. 
X has been diagnosed with severe autism and ADHD however everything has been ok, until recently where X is having major meltdown, hurting himself, screening etc, this neurodiverse meltdown is lasting for over 2 hours and there is nothing we can do to stop or help. 

Anyone know where I can go for help please, what’s the best way to support X etc.

thank you
