A lot of people have it. /small wave/ Or something that impacts behavior with other people. It's not really a big deal in terms of how people think of you.
What you might want to do is figure out what it is actually causing you trouble with, and practice that hard. Social interaction, possibly. Read up on how people work (I had a book "The Unwritten Rules of Social Relationships" by someone else of this diagnosis), study facial expressions and practice ability to make good eye contact, deliberately train your ability to empathize. Discipline, possibly. Figure out if it is causing any issues with your work habits and make a plan to remedy them. I don't know what it is for you; those are the two that are most obvious problems for me. Edit: Of course I also dealt with being diagnosed with dysgraphia by trying to write constantly every day, heh, so I may overtrain against my weaknesses.
There's no reason to have different expectations of yourself, or for people to have particularly different expectations of you. However, it is a diagnosis because it can cause challenges, so use getting it to your advantage! See if you can tie any challenges you have to it, and find strategies other people with it have used against those to better yourself. This one can entail some strengths as well, so enjoy those and leverage them. Diagnoses don't change anything about you - they just help you figure out what to do about it.
