Anyone know the best way?

I spoke to my GP today and outright asked.  I've been voluntary once before when suicidal and discharge coded Acute Stress Reaction and I was let on my way.  I'm in a total mess again.  Historical (2007) diagnosis of emotionally unstable personality disorder (I think DSM V version of borderline).  GP isn't in tomorrow but I'm due to see the student drs and there was talk of crisis team who I have never had a good experience with.  I'm not under a CMHT and have no CPA in place.  I have been before and it becomes iatrogenic.  I'd just like somewhere safe to sit and sleep until I can find a future again and then some therapy to help me get there.  Until then, I've hidden the sharps and all of the pills except benzos....I have an emergency risperidone that I'm contemplating though.
