They do care. Open up.
You can't generalize the stories of those who choose to murder themselves, but I'm thinking about those that bootle up their feelings.
Those that put on a smile and refuse to worry their loved ones about their depression, mostly for not having to discuss it. Kinda coward way, because it's hard, really hard to go to those who love you and say that you're thinking about killing yourself.
Could you suffer to ask yourself it everytime they put their eyes on you, they're thinking about your deathwish?
