I got my dx of BPD extremely late but my characteristics / tendencies only kind of tend to flare up when I'm faced with extreme life events. We're just all so different in the way we represent, which is why I kind of think you were diagnosed / misdiagnosed like I was too.
Don't worry too much about the label. That's insignificant nonsense. That's just a term out therapists or doctors need to "define" us as in order to help us with the best treatment. Don't worry about it. You're still the same person today as you were before you woke up on the day when you were labeled. So it's all good. You're not the label. You're the person (who just so happens to incidentally have BPD - that's all).
We get you here.
So keep posting and we'll listen
Hang in there!
