My friends have gotten their periods and boobs, so why haven't I?

Just to tell you something you already know and have heard a million times, everywhere, from every adult you’ve ever met: We are all individuals. That’s what makes us great! As Dr. Scott points out, “you’re going to go through this journey on your own clock– there will always be someone who is going through it faster or slower. Neither one is better or worse. Try not to compare yourself with others. You can talk to your friends and be excited for them, but everyone is different and unique.” In other words, don't worry—the boobs will come. Eventually!
