I'm truly sorry to hear about your friend. I'm sorry for the pain you go thru now.
People who find themselves at the brink often think there is no other way, that no one could understand. Like you said, connecting with others--talking with people about what is going on--and finding hope is so very, very important.
If a suicidal person can't figure out where to start, check the phone book under Social Services or Crisis Intervention. If for some reason something isn't listed there, call the Salvation Army and they can give assistance by connecting you with resources. One could even post something in this thread, if nothing else!
All of these agencies and networks exist because depression and suicide are not so uncommon. And folks who don't give in to suicidal thoughts and eventually escape that vortex are also more common than we know. There are more people who 'understand' than one could guess.
