Welcome to NT and sorry to hear about your situation. Some of the symptoms you describe sound like your nervous system is "stuck" in fight-flight mode. This can happen with TBI. Researchers have linked TBI with vertigo, not always as an ENT condition, but as a nervous system condition, which your ENT doctor may or may not know. See

To calm your system down, try some relaxation exercises and controlled breathing -- breathe in to a slow count of 5, and breathe out to a slow count of 5. I had terrible sleep disturbances after my TBI in 2004 - couldn't sleep past 3 a.m. ever... and my system was stuck in fight-flight mode for years, before I learned how to calm it down.
I have also had terrible vertigo problems - which have come back recently, probably because I've been in high gear for a work project for weeks, now, and my system is fried. The more stressed I am, the worse my vertigo feels.
Best of luck with your recovery.

What happened: Sustained mild TBI #9(+) when I fell down a flight of stairs and smacked the back of my head on the steps. Knocked out briefly, then bounced back and resumed everyday life, as usual. Over the coming year, things fell apart -- lost my job, friends disappeared, wife became terrified of me, money flew out the window, and I had no idea it was all happening, or why. Finally put things together in 2007, when I was researching brain injury for a family member. Have been actively working with a neuropsych and recovering since late 2007, with amazing results I never thought possible. Having another person in your corner makes all the difference.
Symptoms: fatigue, tinnitis, sensitivity to light and noise and touch, insomnia, general pain, headache, attention issues, emotional lability, panic/anxiety, anger spikes, raging behavior, confusion, difficulty understanding, trouble hearing, slowed processing speed, limited short-term working memory, balance & vertigo issues, difficulty reading and learning new things, nystagmus and tremors when tired.
