Having lots of problems with my 13 year old daughter?

I had the very same problem growing up as your daughter. Try doing counseling instead of pills, cause sometimes pills like conserta will make you feel better one week then next week make you feel like death. But like i said try getting her into counseling (make sure you take her inside yourself cause she might not attend), she might disagree on the counselor but let her choose someone she is most comfortable with. Counseling can help get more organized and there is obvisously something bothering her, her mind is probably all over the place, my parents had to have spent 100s of dollars on lost school books. But good luck to you and your daughter
