I don't think it will hurt your career if it gets out. My great uncle was dyslexic and became a great/famous lawyer; obviously you can work around your problems or you wouldn't have gotten to where you are. Find a doctor in your area that specializes in adult ADHD http://www.aafp.org/afp/20001101/2077.html and "tell" them you have ADHD and would like treatment for it. That way they would have to disprove what you say first to get anywhere with you, wouldn't be able to say "depression" if you've tried those meds and they haven't helped, etc.
