The emotional changes you'll experience during puberty may not happen at the same time your body matures. You could feel older before you look older, or the other way around. You'll start to think more like an adult does. You'll begin to make more sense of your feelings, both positive and negative, and express them better. You may get angry a lot easier and go through mood swings. Plus, you may cry more-over little and big things. You may become more self-conscious. You may compare yourself to your friends and feel like something is wrong with you. But there's not. You may feel and act more feminine.
