Many cities have help lines and mobile crisis response teams that serve as an interface between the police and mental health providers and are trained to help people in acute distress.
In New York City, for example, you can call 888-NYC-WELL to connect with mental health professionals.
If you call 911, specify that you are calling about a mental health emergency and request a crisis intervention team if one is available, said Megan Rochford, the director of the National Alliance on Mental Illness HelpLine Operations.
