Because it's an impossibility. There is no real answer to this question. Since there is no Mental Illness or disorder that is simple, you also can't just simply ask "if you could take your MI/PD away would you?"

Let me elaborate. There are so many aspects to my being BPD. I deal with emotional dysregulation, fears of abandonment, bouts of anger, impulsivity... and more. To ask if something could take any of this or all of it away is just unfathomable in my mind.

If I were to look at the traits I have, one by one, that doesn't simplify things either. Take impulsivity -- sure I'd like to be less impulsive but then what is the positive side, as remotely as the positives may come out? Sponteneity. Sometimes, I know not very often, impulsive can be acceptable or even good. About the only one that I can think of that is truly 100% negative, is anger, uncontrolled and unreasonable anger at times. Of course you can't just cure my anger either though. It's tied into my emotional dysregulation and therefore it would have to affect the rest of my emotionalism too. That would mean I would be less passionate, on the positive side. Which means I'd probably lose my passion for art and therefore my creativity too. That's a scary thought.

I could go on but you see my point I hope from this.

No, I would not want to cure myself anymore than I'd want to be a different person altogether. I am what I am and as dysfunctional as I may be, learning to cope with my behaviors is really all I'd like to do.
