Hi Dawn
Just wanted to welcome you. I can't answer your questions, I'm afraid, except to suggest your dr is your first port of call as far as assessment goes - or that's how it would be here in the uk anyway. I did feel, on reading your symptoms, that I also have a lot of them, but my diagnosis is not ADHD - I guess that just goes to prove we need to leave diagnosis to the professionals! Hopefully someone with more knowledge of the US health service will be able to give you more specific advice about how you can go about getting medical help.
Take care, and hope you soon feel at home here.
