I could have described my ds exactly as you have at his age, everything changed in Year 3. He began getting bullied (by children and some adults, one horrible teacher in particular) when his differences weren’t seen as ‘endearingly quirky’ anymore. He developed horrific OCD which we are still battling now at age 15.
He has been suicidal and is now medicated to help with the OCD, it controls his daily life.
I don’t know where we would be without his diagnosis, it helps him to understand himself, answered many questions he had etc him being on the waiting list led us to CAMHS (which I know some people hate and have poor experience of) but we’ve had a wonderful case worker who has saved my little boy. We also have the most supportive CBT therapist currently who tries her best weekly to help ds with his OCD symptoms.
My ds was referred for diagnosis age 5/6 and ended being in a group referred to as ‘the lost list’, children who were awaiting an assessment but somehow slipped through the net and were forgotten about. Ds eventually got his assessment at almost 12.
Nobody knows about ds’s Autism diagnosis except the people he wants to know including minimal family members. He finally made some lovely friends and he came home one day and told me he had told a couple of them he’s autistic and he said their reaction to it was lovely, kind of a ‘no shit Sherlock/we don’t care’ way.
There is not a huge amount of support out there in the day to day, there is no huge change in your child, the family or everyday life the day after diagnosis but I do believe it is important. I know some people see it as a label but we’ve never seen it that way, your child is still the same person they were before diagnosis. Ds has a reduced timetable at school (it was that or drop out completely) and has certain passes in school that help him while he’s there.
I would not refuse an assessment especially now when the wait, I’ve heard, is horrendous. You never know when you will need the diagnosis. You don’t have to tell a soul but it’s there if/when you need it.
Ds’s diagnosis was forwarded to our GP and his paediatrician. It was not sent to school, I decided to send the ‘short’ paperwork confirming diagnosis to his head of year but did not share the ‘long’ paperwork due to all the sensitive, personal information in there. We previously had a confidentiality breech at primary school so I would never trust another school with such sensitive information again.
Best of luck OP
