Hello Shadix: I'm not really in a position to tell you if what you're experiencing is considered to be part of any other conditions besides NPD. I know I certainly have lots of desires for things & I don't really know what I'd do with them if I got them!

To some extent, I suspect everyone has this kind of experience to some extent. Perhaps yours is more troublesome to you than it is to others though. I once had a psych professor in college who said that mental illness behaviors are simply the same behaviors we all have, but carried to an extreme.

My thought, with regard to your concern, is that this would be a good subject to discuss in detail with a therapist. If you can find one who is to your liking, this person can assist you with getting to the root of this problem.

Best wishes...
