They may or may not be symptoms of BPD. I think a lot of us need to realize that symptoms overlap with other disorders.

From the list you posted, it's possible it's BPD. But at the same time, all of those symptoms can happen with a severe depression.

Definitely talk with your T, none of us here can dx you. I know that for me, I was diagnosed after repeated nearly successful suicide attempts, repeated hospitalizations, and a plethora of other things that happened. I fit 9 out of the 9 symptoms on the diagnostic criteria.

But even still, it took a long time to be diagnosed. A PD can't be diagnosed quickly, because you can be in a funk that looks as if you have a PD, but isn't long lasting. PD's are generally constant until the patient enters treatment. BPD can also look like a lot of other disorders (and vice versa). ASPD, BPD, depression, anxiety, PTSD, and a few others that I can't remember all look very similar to one another.

So be patient, and like others have said, don't get hung up on the diagnosis. A label doesn't really help you out. It can give answers, sure, but overall it's not what matters. It's your symptoms that matter.
