One thing we must realize is that THIS (if all serious physical disorders/diseases such as tumors and swelling of the brain) are ruled out) is NOT going to kill us. After doing a ton of research, I've found that anxiety could definitely trigger the chronic unsteadiness/dizzy sensation. While anxiety could certainly make a person feel out of place/in pain, it could NOT harm or kill us.
The best thing to do is to try not to focus so much on the physical symptoms and anxiety. Feeding into it only makes it that much worse and will not benefit you in any way, shape, or form. I've learned that the hard way. I let this unsteadiness control my life to the point where getting out of bed was a chore. I was afraid that if I would get up to walk, I would faint or suffer a seizure/aneurysm. I've been feeling this way since January 23rd. It's March 10th. Have I fainted yet? Have I died yet? No. I'm still here. So what would it hurt to try to focus on the positive rather than dwell in the negative?
I took nearly two years to recover from Panic Disorder, and I fell right back into the hole in merely two months, simply because I feel unsteady. Once again, I am constantly/obsessively searching for symptoms on the web (big no-no for GAD/PD sufferers) and self-diagnosing. So far (according to myself), I've had a brain tumor, epilepsy, bacterial meningitis, MS, Meniere's, nerve damage, CFIDS, and eardrum perforation. When we WORRY so much about things that are likely not happening, we tend to experience the physical symptoms that much worse.
Don't let this ruin/stop your life. Continue doing what you love, even if it means being uncomfortable doing it. Let your mind relax and give your brain the time to compensate for whatever is wrong. It is not worth wasting days, months, and years over this. Just some new two sense ;)
