Finally! This is awesome! I know you think I'm just awful, but seriously, there is treatment that works for BPD, and if you can make your life better, that is fantastic!

I posted before what DBT covers, which is the therapy developed for people with BPD. I think you'd be great at it. It seems like everything you say you have issues with can be addressed in that type of therapy.

In a nutshell, these are the traits of BPD:
1 No sense of identity on her own, completely dependent on others to give her an identity. My therapist described someone with BPD as a jelly bean without the jelly inside - without someone confirming what she thinks about herself, it's as if she doesn't exist.
2 Super sweet when she gets what she wants, but rages beyond all appropriateness when she doesn't. Someone who always seems to stay in the emotional extremes - either loving you to bits, or hating your guts.
3 Communicates in a grandiose manner, arrogant and self-important, assumes everyone will agree with whatever she's going to say, and thinks she has the right to tell other people how to live their lives no matter how personal the matter at hand. Comes off as attention seeking. Extremely poor personal boundaries.
4 My therapist says, if she has a client who is driving her nuts, 9 times out of 10 she's borderline.
