I can completely understand where you are!
I have a DD (14) who has ADD & Aspergers. It took us many years to finally get a dignoises- she was 13. As soon as we started ADD medication we saw a dramatic difference. Her once falling grades were now A&B's. The asperger is harder...but we take it one day at a time.
I also have a DD 8 who has dyslexia. She was dignoise with a learning disablitly in 1 grade and qualified for 'resource' for speech and reading. In second grade we found out that she has dyslexia. She is almost a whole grade level behind in reading.
The best thing we ever did: was hire a private tutor to work with both girls twice a week. Both girls have really improved with the tutors help. Not only did she help the girls improve their skills... she also help us navigate the school system.
If you need any help, just let me know?
