Ive suspected for sometime my 30 year old sister has BPD.  Of course Im not a Dr and we do not have official diagnosis.  I found out today she is cutting, and Im scared and concerned, as this is first i know of any self harm.  Its actually hard to fathom, as we are 18 months apart and i have never suspected this.  Of course, this now further confirms my belief she had BPD and makes me feel she needs help from a professional.  Im constantly in a double bind with her, and if i approach her about needing help im afraid she will use this as a reason to push me away.  I live 4 hours away and im planning to drive up to see her unexpectedly to try and convince her face to face to get help.  I may not give her warning I'm coming, but not sure.  What can i say to help convince her to seek help, assuming she doee have BPD, as i dont want to trigger this episode further or make her feel bad about herself.  Im also calling a professional tomorrow to try and get advice, but can't sleep and maybe could start putting a script together tonight on what im going to say.
