You are very brave, it's just another level of pain when your whole society is against you. At least here in Canada, the cities are safe for atheists. Could you change your religion to like... Buddhist, as their are some atheist Buddhist sects, although I am not sure if there are any in Indonesia... maybe you could get some support that way. But from what I understand in Indonesia conversions from one religion (the one of your birth) to another are very controversial/difficult.
Good luck ^^
