I hope your friend is ok, if you think there is a real risk of her committing suicide, you could consider having her sectioned under the mental heath act, (a police officer above the rank of inspecter can do this). Also the Samaritans have a cheap rate number 0345 ??????, MIND have a similar thing, your local church may also be helpful, in Hull the church run a confidential listening sevice called Crossline, I really hope your friend is ok.john
