My mind is currently overloaded in an underloaded sense

There's a lot on my mind, and it really isn't cooperating with me in trying to get sorted through all of this. First and foremost, hormones - out to get me since 2004. Am I so swayed by urges that I can't think straight? Second, Faith. Someone recently asked me why they should become a Christian. I couldn't reply. This is a gigantic warning bell for me. My excuse is that my reasons for being Christian are personalized to me [gives me meaning/purpose, is the logical thing to do]. But this means that somethings wrong... I really need to think. Third, I'm entertaining the possibility of doing the relationship thing. I don't know yet, though. I just don't know.
