As an ex-Muslim Atheist, How could I survive under an Islamic political regime ?

Tunisia has been mess since the revolution and things do not look the least bit promising . Women everywhere started wearing hi-jab and men began to grow beards all seconding the risen Islamic political movement. It's so frighting. I wish if I could travel abroad but I'm only 17 and still a student. It will take me probably 5 years from now so I can moved out definitively to the US or Europe. My agnostic cousin is experiencing the same fears . Everywhere you go, Islamic influence is evident more than ever before.
