I am not a diagnosed psychopath. I too am searching for answers. I'm in the same boat you are in. Trying to figure it out. But I feel anxious. Its usually only in a situation that involves me or putting me at risk. Others I dont care for. Or going to a new restaurant and not being able to control the situation. I agree with what others have said about it seeming impossible to not feel anything at all. At least for me, i have a Very small range of emotion.
