Citygirl,
The 137 is dedicated to battered women and they have psychologist teams operating 24/7.
Here you'll have any interesting phone numbers

As for your friend (does she speak Spanish ?), maybe can she call them or another number on the page.
If she has : serious psy problems + was abused by her boyfriend + has an history of suicide attempts then she needs to be monitored, in some way, 24 hours a day.
Many suicides are usually just SOS calls but some of those failed attempts can make serious damages (like eating two boxes of aspirin pills can make an hole in your stomach... Hopefully, usually boxes are dosed so that even if you eat one full box you won't die. Too, you can die indirectly : eating sleeping pills, falling asleep, and vomitting while you're asleep and getting drowned that way. Serious issues).
Most of the Consulates have too a social branch (hoping it's not a "bozo" in charge).
What else ? She really need professional counseling, non professional ones could make more harm than good.
