I've been officially diagnosed with body dysmorphia and depression. But I think my main issue is BPD. "The primary features of BPD are unstable interpersonal relationships, affective distress, marked impulsivity, and unstable self-image." "The negative emotional states specific to BPD fall into four categories: destructive or self-destructive feelings; extreme feelings in general; feelings of fragmentation or lack of identity; and feelings of victimization." This sums me up completely. I come across as shy with a natural warmth (been told the latter many times), but I use people to make myself feel better. I've dated guys I had no interest in, but dated them to give me a self-esteem boost, and then tossed them aside. I told them what they wanted to hear, while taking what I needed from the relationships. My feelings are extreme, definitely. If something good happens, I feel amazing. But then if something 'average' happens it makes me feel like shit and I hope for the good things again, or begin feeling suicidal and depressed. I genuinely don't have a clue who I am. I don't know what I'm interested in or what separates me from everyone else. If anything, I'm like the pokemon 'Ditto'. I sometimes get urges to do destructive things and I don't know why. I watched the film 'Girl, Interrupted', and related to the main character so much. Can anyone else relate? Should I bring this up with my psychologist? Does a diagnosis of BPD even change anything?
