Oh wow, so many replies so quickly, thank you all.
I have been on Mumsnet since the dawn of time, but still never figured out how to quote and reply to posters.
I think she was struggling at Uni and several friends of hers suggested she may have ADHD or something else, so being who she is she did a lot of research then took herself off to the Doctor. He was very good and listened and asked certain specific questions, agreed with her and referred her to (wherever). She was on the waiting list for a long time, but the assessment has now been done and it’s confirmed.
She has said that if they offered her medication she would take it, but I’ve heard about what pp said about how it can make you feel deadened and I don’t think she would like that.
She is still at Uni but is now a post-grad, but I’m sure there will be counselling and maybe other support.
As for parental input; well I feel terrible about it now, but it never occurred to me for a second. I was always ultra impressed by her organisational skills, especially around school work. It would all be incredibly neat, notes colour coded and stuck with post-it notes. I now realise that that was how she learned to cope, she taught herself coping mechanisms and there was a shit-load of masking going on. Obviously it’s not my fault as I never even knew there was such a thing, but I still feel bad for her!
Thanks you for the link Stuffragette. And for the suggestion of fish oil, I will pass that on.
And thanks for all the insights Softwonder. DD does get hyper focused but then is also a total flake sometimes, loosing phone, purse etc and when she does she gets really really mad with herself.
If nothing else, as a couple of people have said, the diagnosis will help her to better understand and accept herself. And that is so very important.
