Unless you are seeing a specialist to treat a single set of symptoms, vestibular, etc. , there is no need to tell them every symptom. You have a brain injury. That is all the diagnosis you need. It needs proper quiet rest. You need to slow down and let go of thinking you need to do anything but get better. Just because you can walk and try to talk does not mean you can or should do anything.

Watch the YouTube video series "You Look Great" with your wife.

Read the vitamins sticky at the top. It has lots of good information.

You want to stimulate your mind in a casual, no stress way. Playing cards, doing hand projects, etc.

You are very early in your recovery. Many who think their world has come crashing to an end at 2 weeks have great recoveries by 6 weeks. But, you need to give your brain time.

You may have suffered a subtle upper neck injury. They are almost impossible to diagnose. Pain on the bony spot behind the ears is a common sign. Good straight head and neck sleep and resting posture consistently for at least 6 weeks can help. No chin toward the chest postures.

If you have a recliner, you can get good benefit from it. Sit in it doing simple tasks. If you start to feel tired, put your head back and take a short nap.

Many do well with low dose amitriptyline or nortriptyline before bed to help with headaches and insomnia.

Nothing will slow your recovery more than you trying to be productive. You do not recovery by pushing through. This is not weight lifting where the body breaks down and rebuiilds. Your brain needs low stress with good blood flow and time to heal.

So, Go watch the video series.
