They are very nice. Can also be anonymous. Will check back with you every few minutes to let you know they haven't forgotten you.

Depending on what state you're in, they also have a hotline. They maybe could send a crisis team out to talk to you and comfort you. They might recommend that you go to the hospital if they feel you're bad enough, but sometimes we just need someone to be near us.
