Hey there, it looks like you certainly have some BPD traits: impulsivity, emptiness, self-harm, recklessness, mood swings, craving intimacy but not feeling it, lack of identity, though not all your symptoms are characteristic of BPD. The paranoia you described is not typical of BPD, for instance. It may be related to OCD (I don't know much about OCD). So, it's definitely possible that you have BPD. You could easily be comorbid.

My Dx: BPD + Bipolar 2. I wouldn't rely on a shrink to diagnose you with BPD, due to stigma and insurance reasons (US healthcare does not consider PDs treatable). I badgered my shrink to diagnose me with BPD because I told him I fit every single symptom (not to mention, all the deeper research I've done). But, he refused, and diagnosed me with Bipolar 2 instead (I don't disagree with the diagnosis, but I identify much more with BPD). So, I diagnosed myself with BPD.

So, it's good that you posted here about this. The opinions of fellow sufferers can be just as valuable as that of your shrink.
