Does anyone else completely disagree with that sentiment?

I see it a lot in these communities, and I definitely am not trying to yuck on someone else's yum, but I just don't relate to it. Maybe someone else can explain it better than me?

Like, I feel almost totally defined by borderline. I struggle so much with life because of this disorder. It takes so much time and energy away from being able to focus on normal people things, to the point that I feel unable to live a normal life without a ton of help and therapy.

So I just feel that I really am my BPD.

PS: not trying to stir a pot or anything, it's just a thought I had and wanted to talk about
