Sorry you are so lonely right now. My daughter went through much the same experience in high school. Many times people who are different in any way struggle in the religion, it's just hard to fit into the borg when you are intelligent and the type that questions things. You will have the last laugh though, when the kids at the hall are jumping into an early marriage and getting their window washing jobs, you will be out there living a better life, maybe going to college and then on to a great job. You will also meet other intelligent people who like to question things, and they will be friends who won't dump you because you decide to not be a JW. My daughter has a fantastic job in IT and is happily married, so very revenge of the nerds.
Hang in there, it will get better, high school doesn't last forever.
