Do you have tinnitus?

A few days ago, while I was doing my physics homework, I suddendly heard my ears ringing quite loudly. Now the sound got quieter, but I can still hear it. I've discovered that tinnitus has many causes, but stress and anxiety can definitely make it worse. This may not sound like a big deal, but it's pretty debilitating and scary since there is pretty much no cure. If there is some kind of background noise or I'm not thinking about my ears ringing, I don't notice it, but now silence is annoying, I have this mild but constant headache, and my insomnia is getting worse. Does anyone here have experience with tinnitus?
