OP - this sounds like our DD. We had her tested at least four times since homework starting behind troublesome. The testers were all over the place: maybe ADHD, high I.Q., slow processing skills; no ADHD, exec. functioning. Every tester and shrink had a new set of $$ recs and services to sell. I finally found a good tester, asked for blind testing (told him he could not see earlier testing or teacher's comments) and we finally got the correct diagnosiss which was then asperger's. Now an adult, the diagnosis is spot-on, but it was hell getting there. Please find a good NT tester - should be at least 3 days of testing and about $3K and find out what is going on. It could anything from vision issues, to reading problems, to adhd, to exec. functioning, to slow processing to something more serious like autism disorders. You owe it to her. She'll only get more depressed. Some kids respond beautifully to anti-depressants and ADHD meds - others not, but you have to start somewhere. Good luck
