Hi!
I'm not diagnosed with BPD but I'm about to see a therapist bc I possible have some traits or the disorder, so my opinion is not from someone who knows a lot about BPD.

I'm sorry you have to deal with all that suffering.
In my opinion it's very good that the borderline issue was mentioned by your therapist. It means you are being open enough with him/her. And that you overcame this embarrassing feeling to talk to your therapist about all your symptoms. I read that there are many symptoms that are unoticed bc the patient is not awared of them.

I encourage you to go on talking to your therapist about the topic and see if (s)he can help you in therapy or recomends you a more specialized therapy.

I wish you soon find your answers. Good luck!
