Dismissed from ADHD Assessment, Now What?

I went in for an ADHD assessment after symptoms had gotten really bad once I started college, but I was quickly dismissed because my parents didn't think I had it (they answered 10 questions while I answered hundreds) and because I had good grades growing up and wasn't super disruptive. They told me it was just depression and anxiety, which I have dealt with before, but I've found that after treating those I still have the same attention concerns and symptoms I had that lead me to go into the test. I insisted none of the problems weren't new, but were just stronger now and it doesn't feel like anyone listens. Any recommendations?
