Please know—- BPD is quite complex and it’s nine criteria has hundreds of possible combinations. And if you add in the HPD criteria, the possible combinations of both of them reach the thousands. 
You very likely do not have the same combination of symptoms— which really does change everything. 
We are not all the same. And just because you disagree with Heard’s actions, and also relate to some of them, doesn’t mean you are the person Depp’s team is accusing her of being. 

when we speak in general terms, yes individuals w/ BPD can sound very similar. 
but in non general terms—we all have different experiences, triggers, actions, intentions, beliefs, values, attitudes, bias…. The list goes on. 

You have your own perception, and reasoning. Your own unique journey to this point in time. And unless you are a rich movie star, with both the same symptoms of BPD and HPD as Amber Heard, then there is no reason to compare.
