It sounds like you're doing great!
One of my main symptoms is dizziness. When I get my heart rate up I get dizzy a few hours later. I see that you are doing yoga and going to the gym, but you are not symptom free. Does this physical excersice effect you at all?
My Concussion specialist is still advising me to not work out untill i a symptom free at rest. I really wish I was in your position and could still work out

.
Anyways, happy to hear you are doing well.
