My almost 3 year old was diagnosed with a neurological stutter.

My almost 3 year old was diagnosed with a neurological stutter. My almost 3 yr old daughter was diagnosed today. She began stuttering not even two weeks ago and it has become severe in just 12 days. She was speaking in paragraphs and now can't get out simple sentences. She will begin speech therapy next week. In terms of diagnosis out there, I know there is much worse, but I am very upset. Any other parents out there with tips, support, etc? What can we do to help her?
