I'm too afraid to run away from home but I want to?

So for the past while I've been thinking of running away from home. I'm planning on leaving as soon as possible. However I have already attempted to leave twice and something stopped me both times. I hate my parents and entire family. I don't have many friends that I actually like and trust (I only have 3). My parents aren't abusing me so don't waste your time telling me to call some place if they are. They are just WAAAAAY to restrictive and are horrible parents considering everyone I knows parents. By the way I'm 15. I don't drink, smoke, or do any drugs so there's really no reason my parents should watch over me like a newborn baby. I have a bed time of 10:00 EVERY NIGHT. I'm only allowed 1 can of pop/soda per day. I'm not allowed to have a girlfriend. I'm not allowed to have a lighter (I like fire.) I'm not even allowed to keep a bullet just for fun and nobody in my family has a gun. I have two folding knives and one 12 inch baton hidden in my room so that my parents won't find them. They said if they ever found a weapon in my room that they would call the cops. They don't believe me about ANYTHING. I'm not allowed to leave the house when my parents aren't here and they call me every hour to make sure I'm still here. If I post something (even a joke) on facebook about hurting someone or someone dead they freak out on me and get me to delete it. I can't even joke around saying stuff like homie, dawg, and brutha to my one friend... But I've explained to my mom IT'S FOR FUN. She doesn't care. I'm not allowed a pet and I want one really badly. I'm not allowed to have a password on my Laptop, Ipod or any electronic devices. They constantly check my room to make sure that I'm not hiding anything from them. My parents yell at me for the stupidest things and get even more mad when I yell back at them (I have big anger and tolerance managing problems) If I sell something and decide YEARS later I want it back they won't let me get it. If I don't do what they say they threaten to take my X-box 360, Laptop, Cell Phone, and Ipod away but so far they don't go past the threat. They won't let me have energy drinks. I'm basically a slave to whatever they want me to do. I don't love them, I don't like them. I just hate them, I hate society, I hate most people in general. The only ones I like are my three friends. I've tried to run away twice as mentioned earlier but I'm unable to as soon as I grab all my stuff. Any thoughts on ways to help me? Please don't bother trying to convince me not to go, I've dealt with enough of that the last time I posted one of these. Thanks, sorry this was so long and in one big clump :P.
