What seems easy often is not.
Ever heard "You can only control what you do, you can't control others."?
Ok - same is true here...
You can say "I want to kill myself, please help."
They may say "Aww, it's not that bad. What'd you think of last night's episode of The Big Bang Theory?"
You can say "Last night I SI (in more specific terms)"
They may just look at you and then pretend they never heard anything.
You can tell people over and over but until they are ready and willing to hear you - you will never be heard.
The minute you act out - you become noticeable but you are also the lowest of the low or meant to be pitied.
It's a no win situation many times.
