I am going to have to watch this series. I was suicidal as a youngster (from at 8, being comfortable with the idea of just ceasing to exist, to my teens and slightly beyond, being actively interested in killing myself). I was bullied (though I didn't think of it that way at the time) all through my school years, and I remember why I didn't tell anyone - because I knew it would just make it worse. Telling adults, if all that could happen is the kids doing the bullying would get a stern talking to, without actually removing either me or the others, from the situation? Yeah, that wouldn't go well. For me.
The only thing that stopped me from killing myself was that I realized I would only be making the lives of my loved ones worse. I'm not sure that everyone in a suicidal state can get to that realization.
I had close friends and parents I could talk to about "anything" (sort of - now, at 42, I'm starting to come to grips with the notion that my mom may not have been as unconditionally supportive and loving as I, or she, thought), and they really didn't have any idea of the darkness I was trying to keep at bay.
So yeah. I keep hearing about this show - I'm definitely curious!
