Just continue move and stretch several times per day.
If you have a Rock Steady Boxing program near you and can go, I would suggest that you get involved for your physical training and it makes for a good connection to like minded goals for most people. As far as tiredness goes it is different for everyone. I usually take a short nap in the afternoon, and try to get a standard time to go to bed and to get up. Best wishes to you on your journey.
