Starting to think you have anxiety? I think that boat has long sailed. Dying of an ear infection? Facebook is not a research source. Googling symptoms just scares us, because symptoms can mean a lot of things or nothing at all. Current guidance for ear and sinus infections is to not use antibiotics at all unless they don't go away on their own, which they virtually always do, so as to reduce the overuse of antibiotics that has become a problem in health care. I also wonder -- did you say you were on a course of antibiotics you hadn't completed and your doctor told you to just stop? I think I know why a doctor would say that, which is that many people get side effects from antibiotics and they are harmful long-run to parts of the immune system. But once you start a course you generally have to finish it. But let's say everything was done fine -- you're worrying about everything. That's anxiety.
