Here are two more links for you, Beaver.

They're for an organization called the Samaritans. They're trained volunteers who deal with people in emotional distress, including suicide.
They don't judge you, it's confidential and you're left free to make your own choices.

Phone: (England and Ireland only) open 24 hours a day seven days a week

This second address will give you a complete list of phone numbers, if you're close enough to call. It's great when you have nowhere else to go. I've dealt with them myself.

Good luck.
