I've stopped feeling emotion..?

I know I won't get a definite diagnosis or anything here, but I'm just looking for some ideas. I've stopped being able to feel emotion. Now I "hear" emotions, rather than feeling them. I basically have to "contact" my brain, and my brain speaks the emotion I should be feeling. It's not an autonomic function anymore, I consciously have to have a conversation with myself to determine an emotional response. This may be a dumb question, but is this normal? And if not, what is it?
