I have been diagnosed with Histrionics, but it is in conjunction with BPD.

While histrionics is a part of my illness, my "normal" personality also includes being "emotional, lively, expressive." And I like that about me. I like how people, places and situations can excite me, and I find that it is often contagious, as those around me seem to express their interest more readily and more easily than they might otherwise with someone who has a more staid demeanor.

Obviously, someone with a gregarious personality is going to attract more attention, will create more "controversy" (for lack of a better word), and will always challenge your own emotional "comfort zones."

Don't just write this person off just because she(?) is this way - even if part of her behavior is due to histrionics. If you allow it, she could greatly enhance any experience you share together, just by virtue of her natural exuberance.

Because I have this type of personality, the people that tend to accept me more readily for who I am are those who are already comfortable about who they are themselves, and have strong personal boundaries.

Strong personal boundaries is very important to have when you are dealing with someone with histrionics. And don't forget, there is always degrees in disorders. Just because she may have histrionic tendencies, does not mean she is or will end up being a "nightmare" relationship.

And Perna is right: the more you focus on this, the bigger it will become to you.
