My almost 8year old son is showing these behaviours. School teacher alerted her concerns and he was assessed via school counsellor using Achenbach and Connors assessments, we then saw a paediatrician and a paediatric occupational therapist. He also is showing some sensory processing difficulties and has very poor nutrition as he will only eat 6-8 different foods all bland and easy to eat and lacking in much nutritionally.
He is starting SOS Therapy for picky eaters and a program called Zones of Regulation with the OT and she will also observe him in the classroom.
He will also be seeing a psychologist once these other things get started.
And I probably need to drink more wine!!! It's heartbreaking watching is distress and feeling we have messed him up somehow but at least we have started ad will be able to support him.
I hope this helps,
