Three years ago my mother passed away. I went off to college and my younger sister (now 10) was adopted by who we thought were "family friends". Her "new" family does not want myself or anyone else in our family to be a part of her life. She has expressed to me that she is very unhappy where she is. Since she has been there they have put her on several medications including for ADHD, bipolarism, depression and psychotic something or other. And she is only 10! I will be graduating soon and am wondering if there is anyway that I can get her back or legally is there nothing I can do about it? What do I do?

My guess is that she doesn't want to talk about her feelings about your mother passing away and that is why they are medicating her. I don't know about the legal issue but good luck!

ADHD and biopolarism show their best warning signs in younger children, don't let your angst over missing a sibling deny her a treatment. Over medication is writhe at the moment but it seems they are sending her to all the right doctors. Get the facts before you act.

Be,
Speak with a lawyer. If you cannot afford a lawyer, speak to legal aid. Please remember, you are her sister! You have the right to inquire upon her behalf. Don't let anyone tell you differently. It must be very difficult for you to worry about her the way you obviously do and not be able to have any say in how or who will raise her. I believe you should do what your mother would have wanted you to do. Keep an eye on her.
After all, you come from the same womb.
