I would add a few.

Dos:

Activities that involve hands but not much work. E.g., playing an instrument or cleaning a surface.

Rest. Sleep has been regenerative for me. Take a rest when you need to.

Audiobooks. Listen to books to occupy time but not cause strain.

Meditation/relaxation. Seems like a good idea to me.

Exercise. When able, small amounts of exercise (increased gradually) can be very helpful.

Nutrition. Healthier food means a healthier brain.

Dont's:

Push yourself. If you feel sick, stop and rest. If you want your brain to heal, give it some time.

Be patient. This is almost impossible, but it will require doing as many dos as you can.

Freak out. Almost unavoidable, but try to remain calm.
