By age 18, many teens are feeling a combination of excitement and fear about the future. They tend to be very focused on their friends, social lives, and future. There are a lot of decisions to be made about life after graduation, including potential careers, college plans, or military service paths.
This is a time of changes for how teenagers think, feel, and interact with others, and how their bodies grow. Most girls will be physically mature by now, and most will have completed puberty. Boys might still be maturing physically during this time. Your teen might have concerns about her body size, shape, or weight.
