My parents don't trust me or give me any freedom?

I'm a girl in middle school and I literally have NO freedom. I barely get to hang out with my friends outside of school!!! Everytime I ask to do something with my friends, it's usually a no. Sometimes it even takes them te LONGEST times until I get an answer. They give me all these lectures as if I didn't know these things!!! I've been invited to go to so many places with my friends but I'd always have to decline. They'd ask why and I'm always like "oh I have to stay home and be bored since my parents won't let me go." I also can't go anywhere without a parent, and it always has to be my friend's mom!!! Once I was invites to go to the movies and my friend's uncle was gonna be with us the whole time. I know my friend's uncle and he's really cool, but my parents didn't let me go because "the mom had to be there." I was so pissed off!!! My friend already paid for my ticket, too, which made it even worse!!! I can't walk to school with my friends, which is only like, 5-10 minutes away. It would save them gas and time but noooooo, I can't walk with my friends. I have to be driven by my mom. I can't even have a boyfriend or hang out with guys!!! I know I'm a bit youn to have a boyfriend but I have some guy friends and there all really cool and nice, but I guess the only thing my parents think about is sex. I'm not stupid, and my parents should know that. Their too overprotective and I feel like their taking my childhood away from me. I only have one childhood and I want to enjoy it, but them being so overprotective is killing me!!! Sometimes I just want to move out and run away. I know, they love me and I'm still their little girl. But if they loved me, they would want me to be happy and have a fun childhood, not being locked in my house 24/7 with nothing to do. What should info about my parents? I wanna talk to them about it but then they might end up getting mad, and they get mad REALLY easily. What should I do?
