you most likely will have mood swings. mine are horrible. you will feel like ripping someone's head off then you will start bawling your eyes out then maby youl be fine.
its mainly dramadic mood changes.
there are also other things that may occure too. you may start being mean to your family and friends without meaning it.
moodswings differ from person to person and you should talk to someone or you could get depressed possibly if theyre too bad
hope this helps :)
Adolescence is the age when puberty sets in. Then, many physical and emotional changes take place.
mood, attitude, grades, style
You become mature
Be someone you like neevr change it. Unfortunatley, most adolescent relationsips, such as dating in your teen years 15-18, are not taught in class. These experiences are those you learn in practical life. My best advice to you would be to stick with a partner who is predicable, and responsive to your liking.

The most drastic change is that originally leotards were designed for men. Now they are mostly worn by women. Changes also concern design. Some leos look really sexy :)
No, the media is not the most important influence on adolescent behaviour.In fact friends are the most important influence on adolescent behaviour.You can either chose to follow them, or not to.You can choose to do the good deed, or the bad.You can even choose what sort of friends you want to influence you.

Most fish get very light colored when stressed, but some become very dark. Basically, a drastic color change indicates a problem.
