I went through the same shit. When I was 16, I wanted out, but I had no escape. It's a terrible way to live. I left the JWs at age 18 1/2. I was forced to go for half a year after my 18th birthday. My last meeting was when I gave a talk in the Theocrappic Misery School.
However, there's some things you can do to ease the burden. Have LOTS of homework to keep you away from some of the meetings. The book studies and TMS/Service meeting are the easiest to get out of. Just to make it look like I had tons of homework, I took up writing a journal. It kept me entertained while I waited for my parents to leave for the meeting. I'm now using my journal entries to write an autobiography. To avoid field service, and any confrontation with the elders (from not going out), write fake hours on your report slip. They can't do nothing about it. You also might want to ask to get your job shifts on meeting nights. Making money is better than listening to WT bullshit.
Two years can seem like a long time to wait. Just try and make the best of it until you can get the fuck out. After you're out, you've got the rest of your life to have fun!
