How do you enter a phone number like "1-800-SUICIDE"?

1-800-784-2433 and yes they keep their calls confidential. They are there to help you and to call and seek help is a very mature thing to do. If you are dealing with depression though, I would not try to hide it from your parents. You should let them know how you are feeling and let them try to help you as well! Your parents love you more than anything in this world and they will do anything to help you! The best thing to know is that you will be able to overcome this depression and that there are plenty of people that are willing to help!
