In my state, 211 is a social services directory line. They can be nice to talk to because the number is a 24/7 number. However, they tend to try to give information from their directory. So, you end up with numbers and have to call them to see if they can help you. The phone answerer will sometimes try to give you a number that is worthless to you.
I called them a few different times because they discontinued making the directory public. They make you subscribe to the social service directory on-line in my area. The person tried to give me some numbers to do with employment that focused only on disabled people. I corrected the person and then the person saw that statement in the resource directory. However, it is a good place to start on looking for social services in your area. They do have a pretty good size directory in my area. They seem to work on updating it pretty regularly.
I would suspect that they would be good to talk to if a person needs to talk to a good listener and wants to remain anonymous. They do not ask for a name.
I have not tried to share a thought of suicide with them. So, I am not sure I'd suggest it for that.
A friend of mine almost found a bed for the night through 211 also.
