Supposed to be gifted with words, and i cant even absorb a page

For context, I’m 14 and have consistently scored in the high percentiles on MAP (this year 94th percentile) and WISC V VCI of 133 (99th percentile). Yet, I always felt absorbing content was a pain, rereading and rereading text, and felt like I had absorbed nothing at all. My psychiatrist pointed out possible ADHD, but I am doing very well in school to the point I dropped out from boredom (I was much better in basically every subject than my class’s material had to offer). Now, I’m homeschooled, applying to a gifted school, and still wondering how I’m supposed to be “gifted with words and comprehension” when I literally can’t read books without feeling empty without absorbing the content. Yes, I have a very good vocabulary and I like debate, to write, etc., but I don’t like to read books for the life of me for its sheer cognitive exhaust. I tried adderall (worked but also made me a bit like too alive) and vyvanse right now 20 mg but honestly feels like it barely helps with anything whatsoever.
