What is wrong with me?

I’ve noticed this behaviour before but now it’s getting more concerning. I basically have no interest in people or what they have to say. It’s gotten so bad that it’s even hard for me to stay interested in what my family and friends have to say. To be honest, I don’t even have many friends left because of this. The conversation is boring to me most of the time. I want to be interested, I want to care, but I don’t feel it. And I end up feeling bad because I know the other person can tell I’m not into the conversation. Am I a sociopath? A narcissist? I don’t know anymore.
