Of course you can.

One thing to point out when it comes to any kind of psychological testing. Diagnoses are only as good as your honestly and the professional's observation. I'm not saying the diagnoses are accurate or not, I cannot judge anything, but if we are not totally honest and truthful through the process of being diagnosed, the results will not be accurate either. Just something to everyone to think about I guess. I self-diagnosed my BPD almost a full year before it was "official".
