How can you tell when you're having trouble concentrating on homework because of your MI (symptoms or medication side effects) or because the homework is just really hard?

Does it matter?


I guess for me, it makes me feel better if I know everyone else is having the same difficulties with the homework as I am (in my case, reading for university classes). I guess the other thing is that if it's something to do with my MI, maybe that means there's something I could do to make it easier for me, like take a nap, practice mindfulness, etc.
