I’m a teacher too (retired now). I was diagnosed aged 50. I was well known for being able to deal with the ‘difficult’ pupils – I’m sure because I saw something of myself in them and was able to meet their needs better. I also kept a quiet, very orderly classroom. I was known as ‘Mrs Organised’ – overcompensating for my real self, which came out at home in a big way. Work order, home chaos!
I didn’t tell anyone at work either, but I did slowly educate those who were willing to listen.
