I feel like im choking on water?

You know that feeling when you drink water and it goes down your wind pipe or so it feels like it with the burning nose I'm feeling that. Last night I coughed hard because I had a feeling of muscus but nothing is there is the anxiety?

I had a sore throat before this started and when I breath in you can hear the intake of breath really loud.

I am a hypochondriac anpain symptom drives me into severe anxiety
