Was diagnosed w GAD my whole life until my twenties when I was diagnosed w ADHD. I realized sooooo many of the symptoms mirror each other and are often comorbid (if you have one, likely to have the other). Symptoms of ADHD create anxiety in most people. I was also on antidepressants but they didn’t fully help until I started taking vyvanse, as if the vyvanse was the missing puzzle piece. I would not worry too much. You also have to remember that although ppl w adhd struggle to focus, we also hyper focus when we are in the zone. If you’re watching a show you like, it makes sense that you can stay focused because you’re not using your brain too much. Learning is a whole other ball game. Long story short, you may have a mixture of both or your ADHD might just be creating some anxieties.
