I am finally going to have access to therapy in about one month, and I am wondering about how and when to bring up the subject of BPD.

I've looked into BPD quite a lot, and have repeatedly related to the symptoms. And that's why I think it's important for me to talk about it in therapy, no matter what the output ends up being.

But I've seen so many people testify about the stigma, even with mental health professional. And I am scared.

Is there any moment or way to bring it up that would be best?
And would you mind telling me about your experience if you ever were in the situation of telling a therapist about BPD?
