I'm undiagnosed and pretty confident that I have BPD (I'm horrendousy clingy for starters) yet I see some narcissistic traits in myself, I'm hoping to get diagnosed soon but I want to know If others experience those kind of symptoms. For example I'm quite competitive, In the sport I play I always manage to find some faults even in my best performances.

Or does everyone with BPD suffer with narcissism? If so how does that make the 2 conditions different?
