Hello and welcome!
I am sorry to hear of your cofusing and concerning symptoms. That is difficult I know. I am however glad to hear that you are seeing your doctor for an appointment tomorrow.
This will be good for two reasons...
One, you can rule out any possible physical reason for your experience...or get a definitive dx of anxiety...
...and two, you can then discuss your treatment options for anxiety management.
Let us know how your appointment goes, and how we can support you.
