Oh, we're awaiting dx for dd too - ASD/ADD, hence social struggles. We had no opportunity to speak to the teacher as HT is on the gate daily so was there when she took off (I was mortified !). She'd been reluctant to go for days before it all came out re her friend 'bullying' her, yet she said no-one was upsetting her when I asked at home why she was so sad. It all came tumbling out when HT gently probed her. She was blaming herself for having no friends. Truly heartbreaking.
It's easy to think there's nothing wrong when they seem to be coping and happy, and you can begin to doubt your instincts as you 'normalise' your child's behaviour iyswim. To us dd is just herself and the way she acts is normal for her if I'm making sense. But, then something happens (regularly), that brings us back to earth about why she acts how she does. Seeking diagnosis has been a positive experience for us (backed up by school), as it is so much easier now to see where she's coming from and our understanding of her is so much clearer.
Do you think you will go back down the medical route at all?
