Cass - if you're reading this thread, you know TalkBass cares, man. Add me to the list of those who are available to talk anytime. Also add me to the list of "been there, almost did that a couple times"...
Matter of fact, the thing that made me see it's never a good way out was wandering in and seeing with my own two eyes, somebody (a friend's girlfriend) lying in her own bed crying, all cut up and passing out, from slashing her wrists, and a half bottle of muscle relaxers.
The guy and I had just walked in after getting out of class (this is when I was in college). I made the 911 call, as well as a call to a pharmacist (where I found out that the pills were muscle relaxers) and my friend just held her - and she made it. And eventually, things got better for her, for them.
They have to: when you're at rock bottom the only way you can go is up.
Nobody can say "chin up and it'll get better" and expect someone in your state to believe it, but if you have ever been truly happy in your life, just hold on to the thought of being there again... hell, even if you don't think you ever have been - it's better than sex, better than Christmas when you were 7, better than a new car.
Man, pluck a string and sing your soul out into the night sky. The world can feel you.
Take care.
