I would simply post a teen help line, there are billions and most are toll free and sometime better then the net because they are more privet, I don't know any off hand.

as for the topic, it is apropeat that I post this here. The first story I ever did I have a problem with the first few chapters, that story would be Stained, I began writiting it becuase a author who's name I won't mention.... had yet to update 'Gone From Daylight' on top of the fact at the time there where very few stories out there on that topic.
I don't even think I delt with it in a very tastful fashon and it might be why I never get any input from that story. Needless to say from reading I like a little bit or a lot of the good before you start getting into the bad. If you start building a story line from the bad the reader will get depressed before they get into the story and might stop reading.
In Harry Potter book 5 the mood was set wrong from the beggining and left for a very long road to the end. Till Myr's post above, I thought I was the only one to feel that way.
I think it is best to first start with a someone happy invierment something for the readers to reminis about before hashing out the bad stuff.
but what do I know I'm still a novis that dose a half way decent Draco Malfoy.
