What's up with the suicide hotline?

Because people just don't understand the mind set and though process of a depressed person and they think its so simple to just "snap out" of it. I don't talk to other people about my problems because most people understand/care. Even my "friends" used to brush off my problems and even accuse me of lying to get attention. You won't catch me talking on the phone to some untrained volunteer who knows NOTHING about depression or suicidal individuals.
