When I was a teenager I had an inner and middle ear infection that ruptured my left eardrum. Your symptoms remind me of my own back then!

The problem was that I needed to go on an airplane to get to the Nationals of the Science Olympiad that week. If I didn't go, the team couldn't go. You need two girls on the team to be eligible...and I was the only person good at biology on the team.

My doctor wrote for some lovely oral narcotics and some heavy duty antibiotics. I got to go on the trip...and when everyone else was literally crying from the pressure in their ears...I was singing and joking around. There should be hope for your trip. You just need a doc who will put some effort into selecting meds for you.
