Just feel like it’s worth discussing, even if just with yourself, the concept of passive suicidality.  I’m pretty sure that it’s very common in those with BPD. And it’s something you should be aware of.  It’s when you may not have a plan to end your life, nor a strong desire to, but you don’t care if you die.  There’s a quote from somewhere, “if a car were coming right at me I wouldn’t move out of the way.”  That sums it up perfectly. You’re putting your life up to the mercy of the universe. This is also what enables you to do self destructive things, a lack of fear of consequences because , if I die I die.   

I feel like this distinction isn’t made enough, and we think someone is only suicidal if they have a plan.  There is weight to this. You don’t walk through death’s door, but you bring yourself to his doorstep.  

So, be aware of this in yourself, and be aware of this in your friends.
