I wasn't diagnosed till about 8 years ago. I'd been getting better at understanding myself and other people all my life, very slowly, and I think I accelerated a little after diagnosis, though I wasn't given a therapist or any advice. I think people mature with age anyway, as long as they don't stop learning. But the diagnosis also shook my self-confidence, though that seems to be coming back again. I don't think my traits have changed at all, I just manage them better, and my personality is much as it always was. I never was one for fitting into the NT mainstream, I just wait for the right kind of people to turn up, sometimes they do and I'm fine. I've begun to do better with relationships, I behave in a more mature way. I've probably become a better judge of character. The world of work probably burned me out a little, and gave me a few emotional issues, I managed to hold down a couple of jobs and got out in the nick of time, and built up enough pension rights to just about give me enough money to do everything I need to do.
My sensory issues have always waxed and waned, basically I've remained in relatively good health, I go through a few good years and a few bad ones. It's good not to be so worried about all the little sub-clinical things that I couldn't understand before, they're most likely down to an amplified sense of pain and irritation. Right now it's fairly good.
