I have to echo what everyone else has said.
I mean, I'd never advise anyone that is financially dependent upon fundamentalists to come out as an atheist, and seeing as how you're in Saudi Arabia, it's just flat-out dangerous. I know it sucks, but as a teenager, sometimes you have do things you don't want to because of your parents' wishes. Just go through the motions until you're an adult, and then you can decide what to do.
