I suspect we all have narcissistic tendencies, if it makes you feel better. You have the power to change, now that you know that you are prone to create relationships with people on a superficial basis. Don't submit to being something that you don't want to be, just because there is a "disorder" out there that describes your current attitude. You now know and understand that you want to empathize more with other people, and have more fulfilling relationships with them. That is the first and most essential step! But changing your habits will take time and persistence. It can be done, though. You are obviously NOT alone, because you are not the only person with these traits. The question is: what are you going to do about it? You have all the tools you need to become the person you want to be, you just need to use them. :-)
