Copy/pasted from a friend:
Did you know that if you text 741741 when you are feeling depressed or suicidal, a crisis worker will text you back immediately and continue to text with you? Many people, especially younger folks, do not like talking on the phone and would be more comfortable texting. It's a free service to ANYONE - teens, adults, etc. - who lives in the U.S. It's run by The Crisis Text Line.
