Dear teenager, as many others who have read your post, I am touched by what you have wrote. I’m in between meetings at the place where I work, but I’YH I will set up an email acount to reach me (as well as anyone else who needs support or to network) later on.
You need a good therapist as well as a support group who can help you out. I’m not sure where you live but if you contact priority 1 or mask they will have some good resources for you. As it happens to be, the relative of whom we have been dealing with, his therapists’ wife dealt with girls off the derech and at risk. They have just moved to Israel this past year, but I will contact them and see if they know what sources are available for young women like you.
I have googled a few links, look into them and see if they are of any help to you.

and worthwhile to look into http://www.ohelfamily.org/index.php?option=com_content&task=section&id=6&Itemid=32 although I don’t know if they deal with teens at risk.
