Is it possible for people with BPD to also have narcissistic personality disorder? 

I meet the criteria for BPD, but I also meet two of the criteria for NPD. Like BPD, you need five out of the nine traits for a diagnosis. The narcissistic traits I have are preoccupation with success/beauty/power, and being envious of others. 

When you look at the criteria for both disorders, they seem mutually exclusive, but are they really? Is there anyone in this subreddit who suffers from both? It just seems like an interesting subject to me.
