1 . When you live in total messiness—cookies in your pants draws, and some old New Yorkers or apple seeds in your bed—it's hard to know where to look for when you lose your keys. The other day, after two weeks of searching, I found my keys in the refrigerator. I can't say I was surprised. But I was surprised when I was diagnosed with ADHD（多动症）,when I was a junior at Yale.

According to a new study, 11% of school-age children have received an ADHD diagnosis, a 16% increase since 2007. And rising diagnoses mean rising treatments—drugs like Adderall are more accessible than ever. However, the consequences of misuse and abuse of these drugs are dangerous.

Yet also harmful are the consequences of ADHD undiagnosed, an all-too-common story for women like me,who have symptoms, like disorganization and forgetfulness, which look different from those typically expressed in males.

Dr.Ellen, author of Understanding Girls with ADHD, has found around 4 million females with ADHD are not diagnosed. "The main reason is that the diagnostic criteria were developed based on those hyperactive（过度活跃）young boys taken to clinics, making it difficult for girls to be diagnosed unless they behave like hyperactive boys." Ellen says.

Besides, the idea that young women actually have ADHD often causes skepticism. As a top student,I didn't believe my diagnosis at first. My friends were also confused,and rather certain my doctor was misguided.

"Often, if girls are smart or in supportive homes, symptoms are masked," Dr.Ellen says."Girls will hide their inability to meet social expectations. They see their trouble organizing,and concentrating as character flaws（缺陷）."

These years, I am both embarrassed and exhausted by my struggles to keep track of objects, but drug has helped it and made it more bearable.
