Why is it so hard...?

I'm 14 and a half years old. And i find it's really hard being a teenager ... there is so much drama with your friends... and you're always fighting with your parents. You also want to start making your own decisions, but your parents don't let you have the time. I have heard from several adults that no one could pay them enough money to go back to their teen years. Why is being a teenager involve so much drama and why is it hard?? How are teenagers suppose to act?? cause my mom thinks im different because i sware and i yell and fight with my parents
