Good to see you back...You can understand our scrutiny, it is reasonable and rational. We have received many who are not who they say they are, and to see a BPD case, which is a woman, that is very highly self aware like this is rather surprising. I myself am inclined to believe you, simply because your understanding of the disorder represents something a person would only know from experience.
But you should stay... I could pull your strings here, I understand your condition very well and understand that emptiness, that vulnerability. The manipulations, the instability, all that comes from a kind of desperation you feel. I know why BPDs hurt themselves, a physical pain to bring relief from the chaos in your mind... Just to feel ANYTHING. You do not experience emotions like normal people, you THINK you do because that is how you perceive it, but it is out of tempo. The sociopath in me wants to feed this to you, some false hope...
But instead, I will appeal to your logic... You stay here, you will learn more, understand more, grow more. That is why you are here. In this forum, most people will see you as a manipulative drama queen. I understand your trepidations, but the only way to grow is to confront your demons. Also, look it as a chance to do something altruistic... Here there are a lot of people who have suffered from experiences with BPD. You may have some insight, understanding of the behaviors, understanding of why and how... I think such things may be able to benefit this forum.
But most of all... You are a curious case, and I rarely meet such a self-aware case. I would have you stay out of curiosity. I am one who thirsts for knowledge, particularly in the domain of psychology. If you are as you say, then you represent a very interesting case...
