I'm really sorry to hear that... if you need some one to talk to I will be at my computer today.
I try distraction when I'm falling. Choose some DVDs (because of shortened attention span I choose TV series on DVD) and relax with some yum food for a few hours- or I read (or re read) some trashy fiction. I make sure I go to bed at a good time, take tablets to help sleep, but not to many! I write my worries in a journal and then leave them for another time.
Maybe you can get someone to come round and sit with you for a while, if you feel unsafe please take yourself somewhere you can be safe.
