No idea where you live, but try to see if there is a Phoenix Place in your area.

Take all your belongings to your family - have them store it in the garage, it won't kill them to park on the street for a while.

Pack up clothing & necessities and see how long they will allow you to stay at Phoenix Place until you find a new place to live.

Phoenix Place is a FREE place to keep you safe from yourself during a crisis, and they also keep some people in residential care.

Don't tell them you have nowhere to live, they'll think you're just trying to get free housing. Tell them you're in a deep depression and having thoughts of harming yourself.
