I used to spend alot of my time playing video games and watching tv/netflix, since its advised against that I have just been sitting around while I keep thinking why this has happened and when am i going to get better which I belive is contributing to my anxiety/depression

what are some things i can do while resting that aren't straining on the eyes besides just dwelling on the fact i received this concussion, I started walking everyday but only for a bit because if i go too long it makes my already constant headache more noticable

any advice?
