meds like ritalin and prosac are known to cause violence and sometimes suicidal behavior in some. I am not saying the drugs are doing it for sure, but I would certainly have mus suspicions. I would start by trying to get her of the drugs.
I would ask her questions that show you care. like, "How can I love you better." "How can I show you that I care more about you."
Instead of more pointed questions that point out her flaws, these more positive questions will build a positive foundation. If your questions are going to put her on the defense and she will explode then perhaps you need to try just to rebuild your relationship before you can get too involved and to specific with your concerns. Perhaps you can raise some of your concerns by waying the pros and cons of different choices, tell her you are not going to stop her from a choice, but let her understand that you are not trying to control her but to help her. Sadly many kids don't get that. As a teacher I can tell you that is a frustration to me almost on a daily basis.
