Educational Psychologist

JoJo64

My son is 12 and is in year 7 and has had anxieties and struggled getting him to school since starting Secondary school in September. On the advice of a friend who is a retired social worker I requested a referral to an Educational Psychologist but was told by the year head that they wouldn't as that is only for total refusers. I would like to know if this is correct or can I insist on being referred . I'm at the end of my tether , my son does not have any disabilities apart from this anxiety for school and leaving me but I have mental health issues. Please can you advise me of my rights for my son to see an educational psychologist.
Many thanks
