I am definitely proud of mine.
Dd spent much of her childhood in pain, much of it unable to walk, and on top of that had to deal with doctors and teachers telling her and each other that there was nothing wrong with her, that she was making it up for attention, that it was such an inconvenience to have a disabled child in the class and that they had never had to deal with that before. At the same time, she was also told by experts that her problems were incurable. And by her schools that the rest of life (secondary school, adult life) would be a lot harder and that nobody would put up with her problems once she got there. She had to see her family investigated by Social Services because of her illness.
She has grown up a strong, brave, kind, compassionate human being, with a great sense of humour and without bitterness. She is forging her way in a very competitive and demanding path. Her mental health is fragile, but she deals with that too with intelligence and humour.
Ds was given the same diagnosis aged 10, he had seen what had happened to his sister. On top of this he struggled with school, was the bottom of the class in academic subjects and was the kind who was never picked for football or any other sporty activities either. Wasn't musical, wasn't artistic. The whole but-they-have-to-be-good-at-something thing seemed to have passed him by. Failed his maths GCSE 3 times.
Aged 11, he found his sister after a suicide attempt. Had serious problems trusting adults: he didn't trust his teachers after what the school did to his sister and he didn't trust his parents because we hadn't been able to protect him. 
He is starting his first grown-up job today, having had the sense to leave his Sixth Form college after the first year, starting another course that suited him better, retaking his maths for the 4th time and passing, and leaving college with excellent grades. Also started training all on his own to strengthen his body, plays football every week with mates. Is kind, thoughtful, independent, upright. If I had to describe him in one word, "decent" would be the one. Couldn't be prouder.
