If you have BPD, you wont always feel like you have it, like right now, I feel completely free but something could possibly happen that triggers a BPD reaction in me. So right now neither do I but yes I sure as hell do have it. Right now, I am just stable.

Maybe you should speak to your t more about this and point out why you don't think you have It and if he has more evidence to say you do then maybe you need to start listening to him. Knowledge is power and you have it but are in denial, it will make recovery or treatment difficult.

Of course I hope you don't have it but if you do, it's time to accept it.
