Funny, your profile doesn't mention your 13 year christian lifestyle.
If you're not feeling the joy of living the life prescribed in the bible, then what, you're being lured by the redefinition of fun as published by the 'other one'.
The christian in you (13 yrs correct?)knows you are simply being tested and knows what it needs to resist.

At a fork in the road, your answer is simple.

Make a decision. Which way do you turn.

To your faith? Then return to the ones responsible for your guidance. Get the needed strength to resist the foolishness from HIM, Your religious leaders and fellowship mates.
Make HIM happy and you know your strength will reurn.

To you need for gratification? Then go to it. Indulge. surrender. enjoy(?). Make the other one happy and you know . . .
