Auntie Wonderful

My older daughter has a very strong personality. She's needed it, and it has served her well in life. She dragged herself up from the poverty of her childhood in South Providence to adulthood in a good marriage, with a good career in Watertown. She has a personality that fills the room when she enters it.
She runs over me like a runaway train.
She has very little for me.
My grandaughter has been in my care for 6 years now, and I adopted her over 5 years ago. During that time I have taken her to more than 6 psychologists and 5 psychiatrists to make sure that I knew what I was dealing with and how to deal with it. She is on medication, in therapy, and we have a clear plan on how to deal with her issues to help her through the tough times.
I have also met with her teachers, principals, counselors, and vice principals in all three schools she has attended and attended IEP meetings at the schools so that we could be sure that help would be there for her at all times.
Yet on the girl's recent visit, when she got out of hand for her birth mother (my other daughter), I was informed that I had to have the girl committed to an institution because I obviously couldn't handle the situation (no one in the family could, and it was obvious that both the girl and I were seriously mentally ill), and I was not a psychologist, so how would I know how to deal with it as well as they would in an institution. I was informed that I had obviously not done enough.
After finding out what had transpired at my younger daughter's house, I understood why the girl had lost it and, although her behavior was completely out of line, realized that she had been provoked. When I tried to let the Aunt know this, she told me that I was just trying to make excuses and again demanded that I commit the girl to an institution.
Since I picked the girl up from the trip I haven't had much in the way of trouble from her - well, not more than most people have from 14 year olds, anyway.
