Rest is important. Playing games is fine lol. Doing absolutely nothing is fine.
Just don’t let it get to where not doing ‘the thing’ becomes an issue.
Also, medications OP and help a ton with your executive dysfunction. The world before and after prescribed stimulants is like night and day.

The whole point of ADHD being diagnosed is that it has become a problem. Enough of one that people wait months if not years on a list to be assessed and pay hundreds, thousands of dollars for that assessment depending on insurance or lack thereof. And because of the pandemic shortages, a lot of people have trouble obtaining medication or in my case, they had bad reactions to specific types and need to find ones that work without those side effects. I was fortunate. My therapist was neurodivergent and made sure that I got support even before I was formally diagnosed.
