Did you just flip out at your sister because she borrowed your Xbox to play Barbie World Tour International Dressup and now she lost your controller? Are you feeling mad or super sensitive or super happy, and then you feel very upset? These are called mood swings. And believe it or not, when you go through puberty the hormones that are making changes in your body are also making changes in your mind, and your mind needs time to adjust. So if your parents get very upset with you and they want to know what is going on, part of the reason is due to the fluctuating levels of hormones in your body, and it's all a normal part of puberty.
The other thing I wanted to ask is, are you feeling yourself feeling attracted to people lately, or having some sexual feelings and you're not sure where they come from? This is also a normal part of the development of puberty. And a lot of it has to do with your hormones as well.
The good news is that you can talk to somebody you trust, someone who's been there. Everyone goes through puberty. Everyone knows what you're feeling whether it's mood swings, emotional changes, sexual feelings. Talking to someone you trust is really, really important. You can talk to your parents, but if you feel too embarassed definitely talk to an older sibling, a guidance counselor, your doctor, a coach, a friend, or someone older that might have gone through this before.
If you're angry or upset, try to take a minute before you react. Try to count down from ten to one. Even though it's obvious advice it tends to work. If you take a second you may have more of a level headed response.
And don't forget to exercise and get enough sleep, and try to relax. All of this feels weird and just happening all of a sudden, but your body and your mind will adjust. It's just a normal part of puberty, and you'll get through it just like everyone else.
