The Trigger to my Humanity

I'm caught in a twix between living as the Christian I am, and living as a sinner full of worldly lust. It seems that I have been conditioned to live the good girl life since childhood and growing up in church around only good influence has helped that. Now I'm an adult and the choice is mine to make ... What music do I like, who do I want to hang around, ect.
These past few weeks I have subjected myself heavily to country music, The Vampire Diaries and giving in to whatever my flesh wants. In watching this show, I am finding myself acting like 'I flipped my humanity switch'. Nothing matters. Do whatever you want. I don't care about anything. 
So the question remains, what is the trigger to turn it back on? How do I get back to caring?
