Our bodies don’t come with instruction manuals, and many young women aren’t sure exactly what’s normal and what isn’t. Worse yet, they often suffer needlessly—or put themselves in danger—because they’re too embarrassed to ask their parents or doctor. Now, courtesy of CosmoGIRL!, comes the sympathetic, dependable help they need. Here are actual questions sent in by real girls, with the editors’ carefully researched responses. The topics cover everything from body basics to serious physical problems to mental health. Want to know if a burn will scar your skin? What to do about irregular periods? How to handle a too-visible hickey? Whether it’s really dangerous to be obese? Should you seek counseling for depression—or is there another way to beat the blues? All these and hundreds of other important issues receive the thoughtful, honest answers that every girl wants to know.
