You are normal!

About your ear if you had an infection it must have been paining and if it's paining don't dive... wait to get well first!

Many people would be terrified to go for a drift dive before even being certified as a beginner. It's better to learn to walk before you run... Your next dive should really be direct with your instructor descending to your speed and ease of equalizing... if it's paining dive a few meters up and try again until it works without pain. usually if you can reach the depth of 10m after it will go easy. But if it's paining this means you are still congested or infected... stop your dive and wait until you are completely healed!!

Don't worry, you will become a diver and you will have a lot of fun in your new hobby!

If you don't find a way with your instructor to do it a bit slower you should consider doing another course like a PADI Open Water Diver course. This course will not bring you deeper than 18m and no advance dive like drift dive, deep dive, descent in the blue etc before you are qualified diver. Deep dive (90feet is a deep dive) is an advanced dive.
I repeat you are normal...

If we would post this as a public thread I am sure many other divers would say that this course you are taking is too rough and that they had a much softer experience during there beginner course...
Hope to be able to congratulate you as a new diver or to meet you underwater between 2 Islands...
