So how’d it go? Was he/she able to help?

At least talk to your doctor. He might know of an anti-anxiety medication that would be safe with your other meds.

No advice, but I sympathize. I once sat listening to music while waiting for my flight to board. When there was no activity and fewer passengers in the area than I expected, I discovered that while I had been waiting they changed the gate for my flight. I ended up waiting in Chicago Midway (this was before their big upgrades in the early 00s) for 12 hours. It was hell.
