Welcome.
The worst part about anxiety is that it feeds on itself, but only if you let it do so. I generally have to keep my mind busy on other things (things I enjoy), from the moment I wake up until I go back to sleep. I cannot let my mind dwell on fear or I'd be going insane.
When Hurricane Ike hit our area my sister-in-law stayed with us in our house, she broke out in hives\rashes, but there was a rational reason for her anxiety... You really need to see if there is a clinic in your area that can check you out or else you will just be stressing yourself out due to an irrational fear.
