Do you ever find yourself getting really irritable for no reasons at all? Or suddenly feeling down without knowing why? Going from sadness to anger to joy in a matter o minutes can make many teens feel as though they're losing their grip. But why is the feeling of being on an emotional roller coaster so common among teens?

Dealing with constant change and pressure is part of the answer. Maybe you're starting a new school and not able to see old friends as much. Getting good grades or wanting to be better in sports or other activities can be a concern for many teens. It might feel as though there just isn't enough time to do everything.

Being a teen means struggling with identity and self-image. Being accepted by friends is an extremely important feeling. Teens also may notice, for the first time, a sense of distance from parents and family. You may feel you want to be on your own and make your own decisions, but it can also seem overwhelming and even a bit lonely at times. As fun and exciting as this time is, it also can be a time of confusion and conflict. It can take a while for teens — and their families — to feel comfortable with the transition between childhood and adulthood.

Another important cause for mood swings is biology. When puberty begins, the body starts producing sex hormones. These hormones — estrogen and progesterone in girls and testosterone in guys — cause physical changes in the body. But in some people, they also seem to cause emotional changes — the ups and downs that sometimes feel out of control.

Understanding that almost everyone goes through mood swings during their teen years might make have a better control and easier to handle.

When It's More than Just a Mood
Feeling irritable or short-tempered can be signs of depression. So can feelings of boredom or hopelessness. Many people think of depression as feeling sad, but depression can also bring feelings of moodiness, impatience, anger, or even just not caring. When depression gets in the way of enjoying life or dealing with others, that's a sign you need to do something about it, like talking to a counsellor or therapist who can help you deal with it.

Taking Control
Here are some tips on what you can do that might make those bad moods a bit easier to handle.
Recognize you're not alone: Although not every teen experiences mood changes to the same degree, they are common.

Catch your breath: Count to 10 or do something that lets you settle down for a few moments, especially if you're feeling angry or irritable. Try to look at the situation from the point of view of a wise observer.

Talk to people you trust: Friends can help each other by realizing that they're not alone in their feelings. Talking to parents is important, too. Parents can share their own experiences dealing with bad moods. Plus, they'll appreciate it if you try to explain how you feel instead of just slamming a door. Teachers and counselors are often good resources, and a doctor can help sort through questions about development. Keeping feelings inside can make them seem much worse.
