I can answer a few, taste issues may or may not go away, could be soon or 8months.
Fatigue is normal, you had a major surgery. Balance rest with walking.
Balance will improve everyday.
Sleep will improve, try a tylenol pm (tylenol + benedryl)
The mental distraction and concerns you have are normal. They way I saw it was the energy of my brain was being used to constantly refiguring balance and the new self, so there was less energy put towards focusing thoughts and speech. That will get better week by week.
I had translab for a small tumor, and have had a great recovery. at 7wk sometimes I sit and think "do I feel any different from surgery?" I can't even force myself to want to take a nap anymore! But early on it was even overwhelming to me to read a zoo map and figure out what route to take.
Sounds like you are doing GREAT! Be patient and take care of yourself, and its said if you had facial functions right after surgery, it will return, the timing is unpredictable.
