Hey everyone.

I am in dire need of advice.

One of my close friends is going to die and I have no idea what to do. She has recently been diagnosed with Borderline Personality Disorder.
I have red about this and know about everything about it. I know about her mistakes and do not have any problem with them.

The problems begin when she starts drinking. She will be fine the entire time, but when she gets home things start to change. She would suddenly run to her medication and try to drink as many as she can. When I try to stop her, she says that she hates me and starts to kick and bite me.

I was recently diagnosed with frontal lobe epilepsy with still fits that initiates psychosis. knowing this one when we were drunk we were just talking and suddenly she got a knife and begged me to kill her. First I thought she was joking, but then I saw she was crying. She tackled me to the ground and put the knife in my hand. She then pushed it towards her neck.

She is living with a friend that tells me that this happens very often. I am not angry about anything, I just want to know what to do. I cannot be there everytime this happens and at this rate she will die for sure. I care very much for her, but am totally confused about what to do.

I thought it could be her medication mixing with alcohol, but it started happening before she was on her meds. There is no way she will ever stop drinking, so what am I to do?

I know Borderline includes self-destructive behavior, but it is like she gets a fit or possessed or something. She goes into a frenzy for about an hour. After that she is calm.

Is this part of Borderline Personality Disorder, or can it be something else?

What is the best way to help someone that do not thing there is anything wrong with them?
