HELP! Am I a Sociopath?

I’m pretty sure that there’s something wrong with me but I’m not sure what. I don’t feel empathy or many emotions and I only feel any sort of strong emotion towards one person. I am extremely closed off to people no matter how close they are to me. I feel some guilt when I lie but I will lie when it will allow me to get away with something. I have some minor anger issues but most of the time I don’t feel anything. I’m sometimes paranoid, especially in public places, when I’m alone, or when it’s late at night. Every once and a while I have violent thoughts or ideas pop into my head without warning. I have been told by a few quizzes/online tests that I may be a sociopath. Does these traits seem in line with that?
