Just wanted to tell you that I sympathize

I went through horrible anxiety and panic when I was pg with DD#1. I had never experienced anything like it either. It was like you described and no one seemed to be taking me seriously. I thought I was either going nuts or just going to die from the anxiety- literally I was that on the edge. I actually contemplated going to the psych ward, quite seriously. I suffered through it without meds too since I was too nervous to take them. I was in the ER about every weekend for the panic and to get an ultrasound. I made them page the radiologist to get a real u/s rather than wait to see my doc on Monday. It sucked.

It's an awful feeling and I hate that you have to be there too!

I would definitely not stop taking the progesterone.

Good luck. Please try to hang in there. I know how hard it is.
