I'm a teenager in serious trouble... help!

My supposed best friend was living in a foster home. We did drugs together, and i bought the drugs ONCE. Well, she told her social worker that her foster mom, Glenda, was abusive, then said that I was a bad influence and that I ALWAYS brought drugs to her house and convinced her to do them. I admit I brought the drugs once, but every other time, she already had them, and she was the one who convinced ME to do them, I had been clean and sober, but she wanted someone to do them with. Well now that she's told her social worker that Glenda was abusive and that I gave her drugs, Glenda may lose her license to keep foster kids, and I may go to juvie, because my "friend's" foster dad said if he found out I had brought drugs there, he was gonna press charges, and we talked about it over myspace, so if they look there, they'll find out that I did bring the drugs once, and I may go to Juvie. I understand I made a mistake and I need to suffer the consequence, but what do you think is going to happen?

No matter what happens, admit to doing the drugs as many times as you did, even though Glenda insists otherwise. However, the up-side for you (if there still is one) is the fact that you were there witnessing it. Glenda was not. You can use that against her in court or somewhere else where you're being confronted.

You can also report to the police that Glenda is abusive. If she really is abusive as you say she is, then she deserves to lose her license to keep foster kids.

One thing i've learned in situations like this is to stick with the three D's. Deny, Deny, Deny. If you tell the truth you will go to juvie. But, if you deny at least you have a chance. Personally I think your being paranoid in that probably nothing will happen.
