As an only child, if you are willing and able to put in the work and can find and obtain the appropriate resources, she has a decent chance. A child who can hold her rage for a year and then control when it goes is more likely suffering from Attachment disorder and ODD then the diagnosis listed. Kids with attachment disorder often appear to have ADHD when they do not do to hypervigilence. Now, I've never met this child, this is just MY observation from reading the behavior discription. Obviously, you will be able to tell better what is going on when you get more information.

I'd recommend being sure that the therapists you have are trained in dealing with attachment and trauma issues.
