She does have an enormous enthusiasm for many things in life - she gives 100%. At the same time she can be a total slob when given half a chance, which I find oddly reassuring.
I suspect she has undiagnosed ADHD. Her younger brother is diagnosed with it, and they are so similar, but she has much more drive and is more focused.
When she was younger she was always late for school, and often did badly academically because of disorganisation. Boarding school from 15-18 and university seem to have suited her much better.
She's also luckily not to have any health issues, for which I'm very grateful.
We've had many ups and downs in our relationship, so it's good to have got to a point where we really appreciate each other.
