I think all those issues you list are unrelated and most are minor so try to keep that in mind when you feel panicky thinking that a combo of bad things must be a major problem. For instance:
The throat muscles seem minor to me, and more like just in your imagination from worrying too much. And a 1 minute hoarse voice is not anything to worry about.
Are you doing anything to help you relax your body, if not your mind? Such as exercise, meditation, breathing exercises, therapy? Sometimes even when your anxiety is hard to fix the symptoms you focus on because of it can be fixed. For example, acid reflux is a dietary problem. It is often caused by lying down too soon after eating, causing the acid in your stomach to flow up instead of down and out. The excess acidity is often caused by poor eating habits, not chewing food enough, eating too quickly, eating too much, eating too much of foods that are hard to digest, etc. There are also gently natural remedies that can often help this problem.
