Does anyone know how to get ODD diagnosis in UK? I have an 8 year old with ASD and I'm almost 100% he has ODD as the symptoms have been so so bad lately. His need for revenge is getting to the extreme it's worrying. He even got someone else in school involved in one of his 'paybacks' . It's honestly getting too much to handle. Contantly blaming other people for his bad behaviours. Things got easier to handle after ASD diagnosis so I'm hoping the same happens if my assumptions are true with the ODD.
