hey. yes, you can. i was diagnosed with borderline personality disorder as a teenager and then as an adult once they could stick it to me for real since i was under 18 when they thought i had it. i never agreed with it though.

in the last 12 or so years, i was diagnosed also with dissociation (DID) and OCD. so, it basically all covers everything symptom wise i struggle with. oddly, i have never been diagnosed with complex PTSD even though my symptoms are all very trauma related.

but i have to wonder if it is more the DID and the others (alters) that made it look like borderline personality disorder because during all those years, i was severely dissociated with such severe depression, anxiety and panic attacks, OCD stuff, and self harm then an eating disorder for 7 years in there somewhere. so, i don't know what from all of that was related to what since there are a lot of overlapping of symptoms, variations, reasons for them, etc.

it is very confusing though when you try to sort out what is from what, at least for me. i still cannot figure it out since a lot overlaps like i said and can trigger other things.
