well i have been suffering from insomnia too. still i am. usually music and warm milk before bed helps me. although i try to reduce my time in front of computer at least 2 hours before bed
well i am just like you. fortunately my parent accept me for who i am, dude you should be proud of your self that you are an atheist, for me it's the best decision i have ever made, i'd say you can always decline to participate in church if you really do not want to, but i'd say go with the flow...
