Frustrated
Hello and welcome to the board. :grin:
In doctor, do you mean pediatrcian or fam doctor or a phsychiatrist? If you and doctor are suspecting something more than the ADHD it might be wise to have her evaluated by a child psychiatrist or neuropsychologist.
Have you read the book "The Explosive Child" by Ross Greene? Many parents here find it helpful.
You've found a wonderful place to land with people who care. I'm sure others will be along to add their welcome.
Hugs
