This is to be expected. When you're there, at least for me, when I believed it, I felt afraid, sad because I wasn't doing enough, and determined to avoid the stuff I really enjoyed doing (be that my favorite shows/movies/music or perhaps that girlie site or thinking of someone I was attracted to). There's an urgent need to defend against outside threats. You're fully convinced that you're doing the right thing. Except...it's sad, because deep down you know you can't be who they want you to be.
Fear and insecurity are masked by coldness towards perceived enemies of the 'truth'. I don't know. I could be wrong.
I would also blame it on too much Shasta. I saw a lovely 24-pack of Shasta cans at the store recently. It brought back old memories.
