I get it too and I am not anxious. Went to docs and he said I could be anxious and not even know it or a bit stressed and not realise.

If you really don't think it is that then go to the docs and they will check it out for you. Best to get it checked out if you are so worried.

You will not stop breathing even though it feels like it.

Not sure what the clicking is in the throat so again mention that to the doc.
