Go with a kind of 'interval training' philosophy for the duration?
THIS is a time when turtles win the races after a time? Go slow and steady.
Hang in there, keep your patience under reins and work hard albeit slowly? You will ultimately come out of this super good.
Know? That at times? It really DOES feel GOOD to thunk your head against a wall? Feels SOOO good when ya stop? But, for you, please be cautious?
It sounds as if you have a very bright mind, and believe me, those concussions can really hurt you! A good mind is a terrible thing to lose! As long as we each have our minds and mobility? We are blessed and need to use our blessings such as they are to the fullest!
