I have similar issues with my emotions. They're usually very blunt and I feel like a phony. You should talk to your therapist about doing a personality disorder test, but they can be time-consuming. Also, you should know that it's not so important which or if you fit into any PD diagnosis, you need to look at your traits and overall problems. You could have significant borderline traits but not BPD. I wish you luck and hope you figure it out!
