Good thing you are here girl. Two things are true: you have a mind strong enough to prevent further harm, and you gave me a spark of awakening this morning. It's odd to say it but i was also dead to the world, browsing here at random looking for some advice when your post got my head awake. Maybe a part of us isn't here just to discover what to do in life, but also to be there for each other.
And there's a lot of people in here for you, and this is just ONE little corner of the internet out of many, many more.
I once read this guy when I was.... needing to read something fast, let's say...
http://www.metanoia.org/suicide/
it's a quick reading and reallt worth it.
Meanwhile, keep talking to us. I'd be glad to hear more
