I believe this is true. For what it's worth, I was told by the cosmic consciousnesses that this was the case - especially people on a healing/shamanic part will encounter severely toxic people in need of healing and with important lessons for us.

I seem to be a magnet for borderline personality disorder (6% of the population - watch it!) type of girls.

Once I didn't figure it out until we lived under the same roof. I would classify it as just as hard and painful as a really difficult trip.

3 years later I'm apparently still integrating - a situation that remotely resembled an attack from the borderline girl caused me to uncontrollably cry a river - after thinking I already processed those emotions years ago.

While I really don't want to repeat such an adventure, I did learned A LOT, about "the crazies", about myself, about the effects of a brain growing up under constant pressure. I think these girls also learned lot from interacting with me.

If someone in your life is throwing endless tantrums from nowhere at you, they might be suffering from BPD. Start your healing here: http://bpdfamily.com/tools/articles.htm

Someone has the brilliant signature "Hurt people hurt people, healed people heal people". This is true, but you must pay attention to yourself and how productive the healing is, at some point you might need to cut your losses and escape (this is likely a big part of the lesson they need) before you run out of healing power and get dragged down with them.
