The reading activity is all about your ability to read and understand simple and complex sentences and signs and symbols in a safe and timely fashion. Some mental health conditions do score for the reading activity because it has an impact on their ability to process what they are seeing. Assessors tend to view being too depressed to read as a "choice" rather than a difficulty in actually reading. That doesn't mean you shouldn't put it in. Not reading mail obviously could have a serious impact on your day to day life.
