Anxiety and choking feeling?

Ok so recently I had my thyroid tested because I’ve been having a choking sensation and my doctor thought I had a goiter.

All results were normal (lab and ultrasound) but this sensation has not gone away.

I’ve had GAD (generalized anxiety disorder) since I was a teen and I was managing it well with meds and yoga. I stopped the meds 3 years ago and fitness was enough, but since starting school and driving 4 hours/day 7days/weeek full time student and working. I’m starting to wonder if this choking sensation is just a manifestation of my anxiety.

Thoughts? Experiences?

Thanks all ❤️
