The thing which I don't quite understand is that if you're genuinely in crisis, wouldn't you want authorities to be called? We could get into a debate about the intentions behind suicide but if ringing a crisis team is considered a cry for help - wouldn't the authorities be a means of accessing that help? I'm aware of the variables, useless hospitals, punitive treatment etc but the whole thing sounds like a contradiction in terms to me. Anyway, I hope that whoever you call, they're able to provide you with what you need at that moment - if you're not really sure why you're calling, say so. They should be able to talk it through with you and as long as you try and be clear about what it is you are feeling i don't see why it would necessarily have to end with more serious measures being taken.
