I haven't. And I never will. I'm not a dr

I'm just trying to read about all the different main illnesses to see if she's more likely to have if she has a lot more symptoms that are common in other illnesses

Which she definitely has a lot more symptoms in borderline personality than bi polar. She almost ticks every box

Just for example. She's never ever ever been high or happy. Although there are quite a few symptoms in bi polar. A few main ones are that there are 2 poles. Meaning ups and downs. She only has downs. No ups ever. She also has never had racing thoughts at all. Not even the slightest bit of mania (or happiness even)
Most of the main characteristics of bi polar just don't add up because the main ones in it, she has none of them at all
