Hi Luke,
I have found EXACTLY what you are looking for!! It is a program called "Adolescence - The Stormy Decade."
It explains what your body and mind are going through as you go through your teen years. It is really cool. I have been watching it because my boyfriend has 3 teen girl-monsters, and it is teaching me how to better relate to them instead of nagging them all the time - know what I mean?
Anyway, here is the website of Dr. Ron Clavier, who is the host of the show. Although it is directed at freaked-out parents, it is also great for ones your age, too. He is really funny and entertaining and easy to understand.
When you go to the website, look down the left-hand side and click on "Consulting and Educational Services." Scroll to the very bottom of the page and click on "Download Session Topics." There, it lists the topic of each program. I think #1 and #3 are what you want to look at - they talk about the physical and mental changes of puberty. Each show is only 1/2 hour long, so you won't get bored to death. I don't know if you will get this show on any stations where you are (It is a Canadian station called CLT - Canadian Learning Television).
Anyway, I know you can order the programs. I have sent off an e-mail to see how much they cost. There might be books that you can read by him - he specializes in adolescent psychology and behaviours (cool stuff).
Will post you again when I hear back from the station. Here is Dr. Clavier's website:

Let me know if you have any trouble finding it, or need help finding more info.
Later!

PS - Sorry 'bout the mushy stuff on my other post. I just couldn't help myself. It was soooo (ain't gonna say it!!)
Thought this might help you more than my other message!
