Hi Lisa- I'm Lisa too
Sorry about
your recent struggles. If you do a search at the top of the forums, you will see manyyyyyy posts similar to yours regarding heart fears, tests, ER visits, etc- all of which have boiled down to anxiety.
That's not to brush your symptoms under the rug. They're real and scary. GERD seems to be a real trigger for anxiety because it presents as chest pains, pains down the arms, etc- just like your symptoms!
I'm thinking get your GERD under control (possibly meds/relaxation techniques/diet), & as your symptoms improve, so will your worrying & resulting anxiety.
What you're going through, although it feels scary and is unique to you, is a very common experience many people here have experienced as well.
Best wishes!
Lisa
