Getting anxious isn't going to help your symptoms if you do have anxiety. Take some time outs to breathe and relax...it may not be anxiety. If you want to be actively doing something about your condition to ease your worry, it's never a bad thing to start taking vitamins, cutting the processed sugar out of your diet, and starting a healthier lifestyle.
Watch your breathing too. People with anxiety tend to change their normal breathing patterns and don't get enough oxygen by doing so. If you start to breathe irregularly, you may notice that you start feeling lightheaded....so that is something to watch for.
You can also have your ears checked and cleaned and see if that helps with your balance. As the above poster said, you could have an issue with your jaw called TMJ which can cause an imbalance in the fluids in your ears.
Good luck.
