First off, English is not my native language, so I'm sorry if I get something wrong. I hope this is the right place to ask.


Me and my girlfriend have been together for about a year. It's been great so far with only minor issues. 
After our relationship got serious she told me that she was seeing a therapist pretty much since she was a kid. She also told me about some bad things that happened in her childhood/adolescence. Mentioned something about depressive thoughts and slight OCD-behavior.  


All cool, I understand that and tried to be as supportive as I can, even though it can get tiring. 


Last weekend she had a mental breakdown and has been in the hospital but got released today. She still lives with her mother but will most likely move into some kind of supported housing or to her father since child protective service is involved now. We are both 18 if it makes a bit more sense now. 


Now, about only an hour ago she told met that she has been diagnosed with BPD. I have to be honest: I have absolutely no experience with BPD and not a real grasp of it.
Like I said, I always tried to be as supportive and understanding as possible.


She struggles a lot with fear of rejection, self perception, suicidal thoughts and sometimes self-harming behavior, if that gives more insight.


I'm hoping that some of you might have some advice for me.
Like stuff I should pay attention for, what I should do when she has another mental breakdown, things I should or shouldnt do, things/behaviour that I have to understand?


My current main concern is that I'm doing something wrong.
I'm absolutely open for talking with her about that, but right now I'm too worried about stressing her out too much.


I'm also happy for every piece of literature or any helpful stuff on the internet that will help me understand BPD.

Thank you guys, have a good day.
