I do have BPD and exhibt all but one synptom.
Although I am diagnosed with BPD and it was mega obvious I had it back a year or so ago (and before), my therapist did say a month or so back that I don't exhibt the classic manipulative behaviors in therapy he would normally see. Again, not that I dont have BPD, I do and am on 200mg Seriquel XR to stablize my emotions (which works super well), he was just making a comment that I am not like most BPDers and exhibt more PTSD symptoms in his opinion.
Either way both along with GAD are diagnosed on my medical/mental health records.
It is very dangerous to self diagnose though as many BPD symptoms cross with PTSD symptoms and other disorders. Most times i dont really know what symptom is from what disorder. MANY mental health disorders have cross over symptoms. It is best to be diagnosed by a trained and experienced therapist/PDoc.
