While it is true that it is a lifelong struggle, I wouldn’t say that just because OP does well at work they don’t have it. I wasn’t diagnosed until I was 42. I resisted the diagnosis because I always did well at work and school. I told my doctor that there was no way I could have ADD. But when I looked back there was evidence that I wasn’t doing as well as I thought I was. I changed jobs frequently, but excelled at every job I did. I was a gifted student who refused to do homework, but I did run almost everyday, so maybe that helped in school. Being treated was an eye opening and miraculous experience for me.
