I’m 29 and got diagnosed last year. After years of feeling like a failure and wondering why people who were nowhere near as smart as I was were getting degrees and great jobs and houses and cars, while I waffled along still living like I did at the age of 18, I ran across an article on msn about how females with ADD tend to miss getting diagnosed because our symptoms aren’t as obvious as those of males. I read it and was amazed: it described me and my life! I looked into it and practically had to FORCE my doctor to give me a referral to a psychiatrist who could diagnose me. Then I had to wait four months for the meeting with the psychiatrists.
