Sorry your posts keep getting deleted! Must be very annoying.
I think what you're going through is a really good example of how counterproductive habits can keep us locked in a cycle of fear.
Google will forever spit out the scariest results, no matter how innocuous the symptom. This is the danger of googling. We go on there for a bit of reassurance, but ultimately, we find things that make us more scared, not less. In an ideal world, we wouldn't jump to the Internet for answers, but if all health anxious types could keep themselves from googling symptoms, then none of us would be here.
The chances of you having sudden hearing loss are low. Very low. Next to completely impossible. But whatever is going on with your ear is separate from what's going on with your anxiety. Reassurance seeking, whether through googling, asking questions on just answers, posting here, or even running to the ER—it's all counterproductive. The trick is to remain relatively calm in the face of scary symptoms, and to try and refrain from reacting negatively or fearfully. That's incredibly difficult, but an essential place to get to in your battle with anxiety. The next time you experience a disturbing bodily symptom (I get that ear thing sometimes too and it is unpleasant), try and keep yourself from googling. I know the uncertainty of not knowing what's going on with you will be hard to deal with, but the more you do that, and the more you realize that your body is NOT falling apart, the more calm you'll become. It probably sounds counterintuitive, but trust me—this is the way to get over an anxiety problem.
